Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business, Basis of Presentation and Significant Accounting Policies	Significant Accounting Policies Description of Business Lions Gate Entertainment Corp. (“Lionsgate,” the “Company,” “we,” “us” or “our”) is a global content platform whose films, television series, digital products and linear and over-the-top platforms reach next generation audiences around the world. In addition to our filmed entertainment leadership, Lionsgate content drives a growing presence in interactive and location-based entertainment, gaming, virtual reality and other new entertainment technologies. Lionsgate's content initiatives are backed by a 16,000 -title film and television library and delivered through a global licensing infrastructure. Basis of Presentation Generally Accepted Accounting Principles These consolidated financial statements have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”). Principles of Consolidation The accompanying consolidated financial statements of the Company include the accounts of Lionsgate and its majority-owned and controlled subsidiaries. The Company reviews its relationships with other entities to identify whether it is the primary beneficiary of a variable interest entity (“VIE”). If the determination is made that the Company is the primary beneficiary, then the entity is consolidated. All significant intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. The most significant estimates made by management in the preparation of the financial statements relate to ultimate revenue and costs for investment in films and television programs; the allocations made in connection with the amortization of program rights; estimates of sales returns and other allowances and provisions for doubtful accounts; fair value of equity-based compensation; fair value of assets and liabilities for allocation of the purchase price of companies acquired; income taxes including the assessment of valuation allowances for deferred tax assets; accruals for contingent liabilities; and impairment assessments for investment in films and television programs, property and equipment, equity investments, goodwill and intangible assets. Actual results could differ from such estimates. Reclassifications Certain amounts presented in prior years have been reclassified to conform to the current year’s presentation. Significant Accounting Policies Revenue Recognition Revenue from the theatrical release of feature films is recognized at the time of exhibition based on the Company's participation in box office receipts. Revenue from the sale of DVDs and Blu-ray discs in the retail market, net of an allowance for estimated returns and other allowances, is recognized on the later of receipt by the customer or “street date” (when it is available for sale by the customer). Under revenue sharing arrangements, including digital and electronic-sell-through ("EST") arrangements, such as download-to-own, download-to-rent, video-on-demand and subscription video-on-demand, revenue is recognized when the Company is entitled to receipts and such receipts are determinable. Revenues from television or digital licensing for fixed fees are recognized when the feature film or television program is available to the licensee for telecast. For television licenses that include separate availability “windows” during the license period, revenue is allocated over the “windows.” Revenue from sales to international territories are recognized when access to the feature film or television program has been granted or delivery has occurred, as required under the sales contract, and the right to exploit the feature film or television program has commenced. For multiple media rights contracts with a fee for a single film or television program where the contract provides for media holdbacks (defined as contractual media release restrictions), the fee is allocated to the various media based on the Company's assessment of the relative fair value of the rights to exploit each media and is recognized as each holdback is released. For multiple-title contracts with a fee, the fee is allocated on a title-by-title basis, based on the Company's assessment of the relative fair value of each title. Programming revenue is recognized in the period during which programming is provided, pursuant to affiliation agreements. If an affiliation agreement has expired and our programming is continuing to be aired by the Distributor, revenue is recognized based on the terms of the expired agreement or the actual payment from the distributor, whichever is less. Payments to distributors for marketing support costs for which the Company does not receive a direct benefit are recorded as a reduction of revenue. Cash payments received are recorded as deferred revenue until all the conditions of revenue recognition have been met. Long-term, non-interest bearing receivables are discounted to present value. Cash and Cash Equivalents Cash and cash equivalents consist of cash deposits at financial institutions and investments in money market mutual funds. Restricted Cash Restricted cash primarily consists of amounts that are contractually designated for certain theatrical marketing obligations. Investment in Films and Television Programs and Program Rights Investment in Films and Television Programs: Investment in films and television programs includes the unamortized costs of completed films and television programs which have been produced by the Company or for which the Company has acquired distribution rights, libraries acquired as part of acquisitions of companies, films and television programs in progress and in development and home entertainment product inventory. For films and television programs produced by the Company, capitalized costs include all direct production and financing costs, capitalized interest and production overhead. For the years ended March 31, 2018 , 2017 , and 2016 , total capitalized interest was $7.9 million , $8.7 million , and $19.9 million , respectively. For acquired films and television programs, capitalized costs consist of minimum guarantee payments to acquire the distribution rights. Costs of acquiring and producing films and television programs and of acquired libraries are amortized using the individual-film-forecast method, whereby these costs are amortized and participations and residuals costs are accrued in the proportion that current year’s revenue bears to management’s estimate of ultimate revenue at the beginning of the current year expected to be recognized from the exploitation, exhibition or sale of the films or television programs. Ultimate revenue includes estimates over a period not to exceed ten years following the date of initial release of the motion picture. For an episodic television series, the period over which ultimate revenues are estimated cannot exceed ten years following the date of delivery of the first episode, or, if still in production, five years from the date of delivery of the most recent episode, if later. For titles included in acquired libraries, ultimate revenue includes estimates over a period not to exceed twenty years following the date of acquisition. Investment in films and television programs is stated at the lower of amortized cost or estimated fair value. The valuation of investment in films and television programs is reviewed on a title-by-title basis, when an event or change in circumstances indicates that the fair value of a film or television program is less than its unamortized cost. During the years ended March 31, 2018 and 2017 , the Company recorded impairment charges of $36.3 million and $22.7 million, respectively, on film and television programs. In determining the fair value of its films and television programs, the Company employs a discounted cash flows ("DCF") methodology that includes cash flows estimates of a film's ultimate revenue and costs as well as a discount rate. The discount rate utilized in the DCF analysis is based on the weighted average cost of capital of the Company plus a risk premium representing the risk associated with producing a particular film or television program. The fair value of any film costs associated with a film or television program that management plans to abandon is zero. As the primary determination of fair value is determined using a DCF model, the resulting fair value is considered a Level 3 measurement (see Note 10 ). Additional amortization is recorded in the amount by which the unamortized costs exceed the estimated fair value of the film or television program. Estimates of future revenue involve measurement uncertainty and it is therefore possible that reductions in the carrying value of investment in films and television programs may be required as a consequence of changes in management’s future revenue estimates. Films and television programs in progress include the accumulated costs of productions which have not yet been completed. Films and television programs in development include costs of acquiring film rights to books, stage plays or original screenplays and costs to adapt such projects. Such costs are capitalized and, upon commencement of production, are transferred to production costs. Projects in development are written off at the earlier of the date they are determined not to be recoverable or when abandoned, or three years from the date of the initial investment. Home entertainment product inventory consists of DVDs and Blu-ray discs and is stated at the lower of cost or market value (first-in, first-out method), and are included within other current assets on the consolidated balance sheet (see Note 18 ). Costs of DVDs and Blu-ray discs sales, including shipping and handling costs, are included in distribution and marketing expenses. Program Rights: The cost of program rights for films and television programs (including original series) exhibited by the Media Networks segment are generally amortized on a title-by-title or episode-by-episode basis over the anticipated number of exhibitions or license period. The number of exhibitions is estimated based on the number of exhibitions allowed in the agreement (if specified) and the expected usage of the content. Certain other program rights are amortized to expense on a straight-line basis over the respective lives of the agreements. Programming rights may include rights to more than one exploitation window under its output and library agreements. For films with multiple windows, the license fee is allocated between the windows based upon the proportionate estimated fair value of each window which generally results in the majority of the cost allocated to the first window on newer releases. The cost of original content in the Company's Media Networks reporting segment (see Note 15 ) is allocated between the pay television market and the ancillary revenue markets (e.g., home video, digital platforms, international television, etc.) based on the estimated relative fair values of these markets. The amount associated with the pay television market is reclassified from investment in film and television programs to program rights when the program is aired and the portion attributable to the ancillary markets remains in investment in films and television programs. All the costs of programming produced by the Media Networks segment and included in investment in films and television programs and program rights, net are classified as long term. Amounts included in program rights, other than internally produced programming, that are expected to be amortized within a year from the balance sheet date are classified as short-term. Property and Equipment, net Property and equipment is carried at cost less accumulated depreciation. Depreciation is provided for on a straight line basis over the following useful lives: Distribution equipment 1 — 4 years Computer equipment and software 2 — 5 years Furniture and equipment 2 — 10 years Leasehold improvements Lease term or the useful life, whichever is shorter Building 26 years Land Not depreciated The Company periodically reviews and evaluates the recoverability of property and equipment. Where applicable, estimates of net future cash flows, on an undiscounted basis, are calculated based on future revenue estimates. If appropriate and where deemed necessary, a reduction in the carrying amount is recorded. Investments Investments include investments accounted for under the equity method of accounting, fair value method and cost method. Equity Method Investments: The Company uses the equity method of accounting for investments in companies in which it has a minority equity interest and the ability to exert significant influence over operating decisions of the companies. Significant influence is generally presumed to exist when the Company owns between 20% and 50% of the voting interests in the investee, holds substantial management rights or holds an interest of less than 20% in an investee that is a limited liability partnership or limited liability corporation that is treated as a flow-through entity. Under the equity method of accounting, the Company's share of the investee's earnings (losses), net of intercompany eliminations, are included in the "equity interest income (loss)" line item in the consolidated statement of income. The Company records its share of the net income or loss of certain other equity method investments (see Note 5 ) on a one quarter lag and, accordingly, during the years ended March 31, 2018 , 2017 , and 2016 , the Company recorded its share of the income or loss generated by these entities for the years ended December 31, 2017, 2016 and 2015, respectively. Profit Eliminations. The Company licenses theatrical releases and other films and television programs to certain equity method investments. A portion of the profits of these licenses reflecting the Company's ownership share in the venture are eliminated through an adjustment to the equity interest income (loss) of the venture. These profits are recognized as they are realized by the equity method investee through the amortization of the related asset, recorded on the equity method investee's balance sheet, over the license period. Dividends and Other Distributions. Dividends and other distributions from equity method investees are recorded as a reduction of the Company's investment. Distributions received up to the Company's interest in the investee's retained earnings are considered returns on investments and are classified within cash flows from operating activities in the consolidated statement of cash flows. Distributions from equity method investments in excess of the Company's interest in the investee's retained earnings are considered returns of investments and are classified within cash flows provided by investing activities in the statement of cash flows. Fair Value and Cost Method Investments: Investments in companies in which the Company does not have a controlling voting interest or over which it is unable to exert significant influence are generally accounted for at fair value if the investments are publicly traded. If the investment or security is not publicly traded, the investment is accounted for at cost because its fair value is not readily determinable. Fair value investments are considered available-for-sale by the Company. Unrealized gains and losses on investments, which are available-for-sale and accounted for at fair value, are reported net of tax in accumulated other comprehensive income or loss. Impairments of Investments: The Company regularly reviews its investments for impairment, including when the carrying value of an investment exceeds its market value. If the Company determines that an investment has sustained an other-than-temporary decline in its value, the investment is written down to its fair value by a charge to earnings. Factors that are considered by the Company in determining whether an other-than-temporary decline in value has occurred include (i) the market value of the security in relation to its cost basis, (ii) the financial condition of the investee, and (iii) the Company’s intent and ability to retain the investment for a sufficient period of time to allow for recovery in the market value of the investment. For investments accounted for using the cost or equity method of accounting, the Company evaluates information available (e.g., budgets, business plans, financial statements, etc.) in addition to quoted market prices, if any, in determining whether an other-than-temporary decline in value exists. Factors indicative of an other-than-temporary decline include recurring operating losses, credit defaults and subsequent rounds of financing at an amount below the cost basis of the Company’s investment. Intangible Assets Intangible assets acquired in business combinations are recorded at the acquisition date fair value in the Company’s consolidated balance sheet. Identifiable intangible assets with finite lives are amortized over their estimated useful lives, and identifiable intangible assets with indefinite lives are not amortized, but rather are tested annually for impairment, or sooner when circumstances indicate that the intangible asset might be impaired. Amortizable intangible assets are tested for impairment utilizing an income approach based on undiscounted cash flows upon the occurrence of certain triggering events and, if impaired, are written down to fair value. The impairment test is performed at the lowest level of cash flows associated with the asset. As of March 31, 2018, the Company concluded that the indefinite lived intangible assets included in the accompanying consolidated balance sheet were not impaired. Goodwill Goodwill represents the excess of acquisition costs over the tangible and intangible assets acquired and liabilities assumed in various business acquisitions by the Company. The Company has three reporting units with goodwill: Motion Pictures, Television Production and Media Networks. Goodwill is not amortized but is reviewed for impairment annually each fiscal year or between the annual tests if an event occurs or circumstances change that indicate it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value. The Company compares the fair value of each reporting unit to its carrying amount to determine if there is a potential goodwill impairment. If the fair value of a reporting unit is less than its carrying value, an impairment loss is recorded based on the excess of the reporting unit's carrying value over its fair value. The Company performs its annual impairment test as of January 1 in each fiscal year. Based on the Company's qualitative assessments including, but not limited to, the results of the most recent quantitative impairment test, consideration of macroeconomic conditions, industry and market conditions, cash flows, and the Company's share price, the Company concluded that it is more likely than not that the fair value of our reporting units is greater than their carrying value. Prints, Advertising and Marketing Expenses The costs of prints, advertising and marketing expenses are expensed as incurred. Certain of Starz’s affiliation agreements require Starz to provide marketing support to the distributor based upon certain criteria as stipulated in the agreements. Marketing support includes cooperative advertising and marketing efforts between Starz and its distributors such as cross channel, direct mail and point of sale incentives. Marketing support is recorded as an expense and not a reduction of revenue when Starz has received a direct benefit and the fair value of such benefit is determinable. Advertising expenses for the year ended March 31, 2018 were $654.9 million ( 2017 — $588.8 million , 2016 — $470.2 million ) which were recorded as distribution and marketing expenses. Income Taxes Income taxes are accounted for using an asset and liability approach for financial accounting and reporting for income taxes and recognition and measurement of deferred assets are based upon the likelihood of realization of tax benefits in future years. Under this method, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Valuation allowances are established when management determines that it is more likely than not that some portion or all of the net deferred tax asset, on a jurisdiction by jurisdiction basis, will not be realized. The financial effect of changes in tax laws or rates is accounted for in the period of enactment. From time to time, the Company engages in transactions in which the tax consequences may be subject to uncertainty. Significant judgment is required in assessing and estimating the tax consequences of these transactions. In determining the Company’s tax provision for financial reporting purposes, the Company establishes a reserve for uncertain tax positions unless such positions are determined to be more likely than not of being sustained upon examination, based on their technical merits. The Company’s policy is to recognize interest and/or penalties related to income tax matters in income tax expense. Government Assistance The Company has access to government programs that are designed to promote film and television production and distribution in certain foreign countries. The Company also has access to similar programs in certain states within the U.S. that are designed to promote film and television production in those states. Tax credits earned with respect to expenditures on qualifying film and television productions are included as an offset to investment in films and television programs when the qualifying expenditures have been incurred provided that there is reasonable assurance that the credits will be realized (see Note 18 ). Foreign Currency Translation Monetary assets and liabilities denominated in currencies other than the functional currency are translated at exchange rates in effect at the balance sheet date. Resulting unrealized and realized gains and losses are included in the consolidated statements of income. Foreign company assets and liabilities in foreign currencies are translated into U.S. dollars at the exchange rate in effect at the balance sheet date. Foreign company revenue and expense items are translated at the average rate of exchange for the fiscal year. Gains or losses arising on the translation of the accounts of foreign companies are included in accumulated other comprehensive income or loss, a separate component of shareholders’ equity. Derivative Instruments and Hedging Activities Derivative financial instruments are used by the Company in the management of its foreign currency exposures. The Company’s policy is not to use derivative financial instruments for trading or speculative purposes. The Company enters into forward foreign exchange contracts to hedge its foreign currency exposures on future production expenses denominated in various foreign currencies. The Company evaluates whether the foreign exchange contracts qualify for hedge accounting at the inception of the contract. The fair value of the forward exchange contracts is recorded on the consolidated balance sheets. Changes in the fair value of the foreign exchange contracts that are effective hedges are reflected in accumulated other comprehensive income or loss, a separate component of shareholders’ equity, and changes in the fair value of foreign exchange contracts that are ineffective hedges are reflected in the consolidated statements of income. Gains and losses realized upon settlement of the foreign exchange contracts that are effective hedges are amortized to the consolidated statements of income on the same basis as the production expenses being hedged. Share-Based Compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. The fair value is recognized in earnings over the period during which an employee is required to provide service. See Note 12 for further discussion of the Company’s share-based compensation. Net Income Per Share Basic net income per share is calculated based on the weighted average common shares outstanding for the period. Basic net income per share for the years ended March 31, 2018 , 2017 and 2016 is presented below: Year Ended March 31, 2018 2017 2016 (Amounts in millions, except per share amounts) Basic Net Income Per Common Share: Numerator: Net income attributable to Lions Gate Entertainment Corp. shareholders $ 473.6 $ 14.8 $ 50.2 Denominator: Weighted average common shares outstanding 208.4 165.0 148.5 Basic net income per common share $ 2.27 $ 0.09 $ 0.34 Diluted net income per common share reflects the potential dilutive effect, if any, of the conversion of convertible senior subordinated notes under the "if converted" method. Diluted net income per common share also reflects share purchase options, including equity-settled share appreciation rights ("SARs"), restricted share units ("RSUs") and restricted stock using the treasury stock method when dilutive, and any contingently issuable shares when dilutive. Diluted net income per common share for the years ended March 31, 2018 , 2017 and 2016 is presented below: Year Ended March 31, 2018 2017 2016 (Amounts in millions, except per share amounts) Diluted Net Income Per Common Share: Numerator: Net income attributable to Lions Gate Entertainment Corp. shareholders $ 473.6 $ 14.8 $ 50.2 Add: Interest on convertible notes, net of tax 0.5 — 0.5 Numerator for diluted net income per common share $ 474.1 $ 14.8 $ 50.7 Denominator: Weighted average common shares outstanding 208.4 165.0 148.5 Effect of dilutive securities: Conversion of notes 2.1 — 2.1 Share purchase options 7.5 3.5 3.1 Restricted share units and restricted stock 0.7 0.3 0.4 Contingently issuable shares 1.7 3.4 — Adjusted weighted average common shares outstanding 220.4 172.2 154.1 Diluted net income per common share $ 2.15 $ 0.09 $ 0.33 For the years ended March 31, 2018 , 2017 and 2016 , the outstanding common shares issuable presented below were excluded from diluted net income per common share because their inclusion would have had an anti-dilutive effect. Year Ended March 31, 2018 2017 2016 (Amounts in millions) Anti-dilutive shares issuable Conversion of notes — 5.2 4.0 Share purchase options 11.5 12.1 4.7 Restricted share units 0.2 0.6 0.2 Other issuable shares 1.2 1.2 0.6 Total weighted average anti-dilutive shares issuable excluded from diluted net income per common share 12.9 19.1 9.5 Recent Accounting Pronouncements Accounting Guidance Adopted in Fiscal 2018 Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities : In August 2017, the Financial Accounting Standards Board ("FASB") issued guidance which amends its hedge accounting model to enable entities to better portray their risk management activities in the financial statements. The amendments expand an entity's ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. The new guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The new guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. The guidance is effective for the Company's fiscal year beginning April 1, 2019, with early adoption permitted. The Company adopted this new guidance in the fourth quarter of the fiscal year ended March 31, 2018, effective April 1, 2017, with no material impact on the Company's consolidated financial statements. Employee Share-Based Payment Accounting : In March 2016, the FASB issued amended guidance related to employee share-based payment accounting. The Company adopted this new guidance effective April 1, 2017. The new guidance and the impact on the consolidated financial statements upon adoption are summarized as follows: • Excess Tax Benefits and Tax Deficiencies: Effective on a prospective basis, excess tax benefits and deficiencies that arise when share-based awards vest or are settled are recognized in the income statement. In addition, the new guidance eliminates the requirement that excess tax benefits be realized (i.e., through a reduction in income taxes payable) before companies can recognize them. Under the previous guidance, the tax effects were recorded in additional paid-in capital, when realized. Historically, the Company has not recorded significant excess tax benefits, because such benefits have not been realized. Upon adoption, the Company recorded a cumulative-effect adjustment of $54.3 million in retained earnings for the net excess tax benefits not previously realized. • Statement of Cash Flows Presentation: The new guidance requires presentation of excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity, and requires presentation of cash paid to a tax authority when shares are withheld to satisfy the employer's statutory income tax withholding obligation as a financing activity. The Company applied the change to the presentation of excess tax benefits as an operating activity on a retrospective basis; however, there was no impact to the statement of cash flows since there were no excess tax benefits in the consolidated statements of cash flows for the years ended March 31, 2017 and 2016. The Company has historically presented cash paid for shares withheld to satisfy employee taxes as a financing activity in the consolidated statements of cash flows, and accordingly there was no impact from adopting this aspect of the standard. • Forfeitures: The new guidance provides for an election to account for forfeitures of share-based payments either by (1) recognizing forfeitures of awards as they occur or (2) estimating the number of awards expected to be forfeited and adjusting the estimate when it is likely to change (as is required under the previous guidance). As allowed by the standard, the Company elected to continue to estimate potential forfeitures. • Statutory Withholding: The new guidance increases the amount companies can withhold to cover income taxes on awards without triggering liability classification for shares used to satisfy statutory income tax withholding obligations and requires application of a modified retrospective transition method. There was no material impact upon adoption related to this change. Equity Method of Accounting : In March 2016, the FASB issued guidance that changes the requirements for equity method accounting when an investment qualifies for use of the equity method as a result of an increase in the investor’s ownership interest in or degree of influence over an investee. The guidance (i) eliminates the need to retroactively apply the equity method of accounting upon qualifying for such treatment, (ii) requires that the cost of acquiring the additional interest in an investee be added to the basis of the previously held interest and (iii) requires that unrealized holding gains or losses for available-for-sale equity securities that qualify for the equity method of accounting be recognized in earnings at the date the investment becomes qualified for use of the equity method of accounting. The Company adopted the new guidance effective April 1, 2017, with no material impact on the Company's consolidated financial statements. Intra-Entity Transfers of Assets Other Than Inventory : In October 2016, the FASB issued guidance that will require the tax effects of intercompany transactions, other than sales of inventory, to be recognized when the transfer occurs, eliminating an exception under current U.S. GAAP in which the tax effects of intra-entity asset transfers are deferred until the transferred asset is sold to a third party or otherwise recovered through use. This guidance is effective for the Company's fiscal year beginning April 1, 2018, with early ado

Mergers and Acquisitions

Mergers and Acquisitions	12 Months Ended

Business Combinations [Abstract]
Mergers and Acquisitions	Mergers and Acquisitions Starz Merger On December 8, 2016, upon shareholder approval, pursuant to the Agreement and Plan of Merger dated June 30, 2016 ("Merger Agreement"), Lionsgate and Starz consummated the merger, under which Lionsgate acquired Starz for a combination of cash and common stock (the "Starz Merger"). Immediately prior to the consummation of the Starz Merger, Lionsgate effected the reclassification of its capital stock, pursuant to which each existing Lionsgate common share was converted into 0.5 shares of a newly issued class of Lionsgate Class A voting shares, no par value per share (the "Class A voting shares") and 0.5 shares of a newly issued class of Lionsgate Class B non-voting shares, no par value per share (the "Class B non-voting shares") subject to the terms and conditions of the Merger Agreement (see Note 12 ). The following table summarizes the components of the estimated purchase consideration, inclusive of Lions Gate’s existing ownership of Starz common stock and Starz’s share-based equity awards outstanding as of December 8, 2016: (Amounts in millions) Market value, as of December 8, 2016, of Starz Series A and Series B common stock already owned by Lionsgate (1) $ 179.3 Cash consideration paid to Starz stockholders Starz Series A common stock at $18.00 $ 1,123.3 Starz Series B common stock at $7.26 52.8 1,176.1 Fair value of Lionsgate voting and non-voting shares issued to Starz's stockholders Starz Series A common stock at exchange ratio of 0.6784 Lionsgate non-voting shares $ 1,088.0 Starz Series B common stock at exchange ratio of 0.6321 Lionsgate voting shares 121.6 Starz Series B common stock at exchange ratio of 0.6321 Lionsgate non-voting shares 118.1 1,327.7 Replacement of Starz share-based payment awards (2) 186.5 Liability for dissenting shareholders 797.3 Total purchase consideration $ 3,666.9 (1) The difference between the fair value of the Starz available-for-sale securities owned by Lionsgate and the original cost of the Starz available-for-sale securities of $158.9 million , amounting to $20.4 million , was reflected as a gain on Starz investment in the consolidated statement of income for the fiscal year ended March 31, 2017. (2) Upon the closing of the merger, each outstanding share-based equity award (i.e., stock options, restricted stock, and restricted stock units) of Starz was replaced by a Lions Gate non-voting share-based equity award (“Lions Gate replacement award”) with terms equivalent to the existing awards based on the exchange ratio set forth in the Merger Agreement. Each Starz outstanding award was measured at fair value on the date of acquisition and the portion attributable to pre-combination service was recorded as part of the purchase consideration. The fair value of the Lions Gate replacement award measured on the date of acquisition in excess of the fair value of the Starz award attributed to and recorded as part of the purchase consideration was attributed to post-combination services and is being recognized as share-based compensation expense over the remaining post-combination service period. The estimated aggregate fair value of the Lions Gate replacement awards to be recorded as part of the purchase consideration is $186.5 million , and the estimated remaining aggregate fair value totaling $43.3 million will be recognized in future periods in accordance with each respective award’s vesting terms. The fair value of the Lions Gate replacement restricted stock and restricted stock unit awards was determined based on the value estimated for the Class A voting shares and Class B non-voting shares as of the acquisition date as discussed above. The fair value of Lions Gate replacement stock option awards was determined using the Black-Scholes option valuation model using the estimated fair value of the Class B non-voting shares underlying the replacement stock options. For purposes of valuing the Lions Gate replacement awards, the following weighted-average applicable assumptions were used in the Black-Scholes option valuation model: Weighted average assumptions: Risk-free interest rate 0.39% - 1.83% Expected option lives (years) 0.01 - 5.50 years Expected volatility 35% Expected dividend yield 0% The risk-free rate assumed in valuing the options is based on the U.S. Treasury Yield curve in effect applied against the expected term of the option at the time of the grant. The expected option lives represents the period of time that options are expected to be outstanding. Expected volatilities are based on implied volatilities from traded options on Lions Gate’s stock, historical volatility of Lions Gate’s stock and other factors. The expected dividend yield was zero since the combined company had suspended the quarterly dividend. In connection with the Starz Merger, Starz received demands for appraisal from purported holders of approximately 25.0 million shares of Starz Series A common stock. Neither the Company nor Starz has determined at this time whether any of such demands satisfy the requirements of Delaware law for perfecting appraisal rights. At any time within 60 days after the effective date of the merger, or February 6, 2017, dissenting shareholders had the right to withdraw their demand for appraisal rights and accept the merger consideration in accordance with the Merger Agreement. The Company received notices from dissenting shareholders withdrawing such demands totaling 2,510,485 shares during that 60 day period. See Note 16 for a discussion of these proceedings. Should the pending appraisal proceedings reach a verdict, stockholders that are determined to have validly perfected their appraisal rights will be entitled to a cash payment equal to the fair value of their shares, plus interest, as determined by the court. The amounts that the Company may be required to pay to stockholders in connection with the pending appraisal proceedings is uncertain at this time, but could be greater than the merger consideration to which such stockholders would have been entitled had they not demanded appraisal. As of March 31, 2018 , the Company has not paid the merger consideration for the shares that have demanded appraisal but has recorded a liability of $869.3 million that is included in current dissenting shareholders' liability on the consolidated balance sheet for the estimated value of the merger consideration that would have been payable for such shares, plus interest accrued at the Federal Reserve discount rate plus 5% , compounded quarterly. The liability is classified as a current liability as of March 31, 2018 based on the timing of the scheduled trial set to commence in the second half of fiscal 2019. Allocation of Purchase Consideration. The Company has made an allocation of the purchase price of Starz to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair value as follows: (Amounts in millions) Cash and cash equivalents $ 73.5 Accounts receivable 254.9 Investment in films and television programs and program rights 851.9 Property and equipment 121.4 Investments 12.1 Intangible assets 2,071.0 Other assets 139.9 Accounts payable and accrued liabilities (143.1 ) Corporate debt and capital lease obligations (1,013.1 ) Deferred tax liabilities (713.6 ) Other liabilities (165.0 ) Fair value of net assets acquired 1,489.9 Goodwill 2,177.0 Total purchase consideration $ 3,666.9 Fair Value Estimates: The fair value of the assets acquired and liabilities assumed were determined using income, cost and market approaches. The fair value measurements were primarily based on significant inputs that are not observable in the market and thus represent a Level 3 measurement as defined in Accounting Standards Codification ("ASC") 820, other than the long-term debt assumed in the acquisition. The income approach was primarily used to value the intangible assets, consisting primarily of acquired customer relationships and tradenames. The intangible assets acquired include customer relationships with a weighted average estimated useful life of 17 years and tradenames with an indefinite useful life (see Note 6 ). The fair value of customer relationships was estimated based on the estimated future cash flows to be generated from the customer affiliation contracts considering assumptions related to contract renewal rates and revenue growth based on the number of subscribers and contract rates. The earnings expected to be generated by the customer relationships were forecasted over the estimated duration of the intangible asset. The earnings were then adjusted by taxes and the required return for the use of the contributory assets and discounted to present value at a rate commensurate with the risk of the asset. The fair value of tradenames was estimated based on the present value of the theoretical cost savings that could be realized by the owner of the tradenames as a result of not having to pay a stream of royalty payments to another party. These cost savings were calculated based on the hypothetical royalty payment that a licensee would be required to pay in exchange for use of the tradenames, reduced by the tax shield realized by the licensee on the royalty payments. The cost savings were discounted to present value at a rate commensurate with the risk of the asset. Investment in films and television programs include the cost of completed films and television programs (including original series) which have been produced by Starz or for which Starz has acquired distribution rights, as well as the costs of films and television programs in production, pre-production and development. For film and television programs in production, pre-production and development, the fair value has been estimated to be the recorded book value. For completed films and television programs, the fair value was estimated based on forecasted cash flows discounted to present value at a rate commensurate with the risk of the assets. For tangible capital assets held under capital leases the income approach was utilized in valuing the tangible capital assets, including the satellite transponders and the real property, under a right-to-use scenario. The fair value of the capital asset was estimated by forecasting a market lease rate over the remaining term of the contract and discounting the payments using a market participant lease rate reflective of the riskiness of the asset. The fair value of the capital lease liability was estimated by forecasting the contract lease rate over the remaining term of the contract and discounting payments using a market participant debt rate reflective of the riskiness of the lessee. We estimated the fair value of the asset retirement obligation by utilizing an estimate of cost to retire the asset, inflating it to the end of the contract term and discounting it at a market participant debt rate reflective of the riskiness of the lessee. The cost approach was utilized in valuing the tangible personal property using standard methodologies to estimate a replacement cost new and depreciation effects for each asset. Replacement cost new was estimated using historical costs and acquisition dates of the assets along with inflationary measures specific to the types of assets included in the valuation. Depreciation effects encompass physical deterioration, functional obsolescence, and economic obsolescence. Replacement cost new less depreciation results in an estimate of fair value when using the cost approach. The fair value of program rights has been assumed to be the recorded book value, based on an assessment that such content is acquired or produced at fair value and aired over relatively short periods (a few years) and thus the amortization of the cost reflects the decline in the fair value of the content over time. As part of the acquisition, we assumed and immediately extinguished Starz's senior notes, which had a principal amount outstanding of $675.0 million , and Starz's credit facility, which had an outstanding amount of $255.0 million (see Note 7 ). The former Starz senior notes were adjusted to fair value prior to extinguishment using quoted market values, and the fair value of the outstanding amounts under Starz's credit facility were estimated to approximate their carrying value. Deferred taxes were adjusted to record the deferred tax impact of acquisition accounting adjustments primarily related to intangible assets. The incremental deferred tax liabilities were calculated based on the tax effect of the step-up in book basis of the net assets of Starz, excluding the amount attributable to goodwill, using the estimated statutory tax rates. Goodwill of $2.2 billion represents the excess of the purchase price over the fair value of the underlying tangible and identifiable intangible assets acquired and liabilities assumed. The acquisition goodwill arises from the increase in the combined company’s content creation capability and enhanced scale to its global distribution footprint across mobile, broadband, cable and satellite platforms. In addition, the acquisition goodwill arises from the opportunity for a broad range of new content partnerships and accelerates the growth of Lionsgate and Starz’s over-the-top (which primarily represent internet streaming services and which the Company refers to as “OTT”) services, as well as other anticipated revenue and cost synergies. The goodwill recorded as part of this acquisition is included in the Motion Pictures and Media Networks segment (see Note 6 ). The goodwill will not be amortized for financial reporting purposes. An insignificant portion of goodwill will be deductible for federal tax purposes. Pro Forma Statement of Operations Information. The following unaudited pro forma condensed consolidated statements of operations information presented below illustrates the results of operations of the Company as if the Starz Merger and related debt financing (see Note 7 ) occurred on April 1, 2016. Year Ended March 31, 2017 (Amounts in millions, except per share amounts) Revenues $ 4,323.7 Net income attributable to Lions Gate Entertainment Corp. shareholders $ 148.4 Basic Net Income Per Common Share attributable to Lions Gate Entertainment Corp. shareholders $ 0.74 Diluted Net Income Per Common Share attributable to Lions Gate Entertainment Corp. shareholders $ 0.71 The unaudited pro forma condensed consolidated statement of operations information does not include adjustments for any operating efficiencies or cost savings, and exclude $70.9 million of acquisition-related costs that were expensed in restructuring and other expenses during the year ended March 31, 2017. Good Universe On October 11, 2017, the Company purchased all of the membership interests in True North Media, LLC ("Good Universe"), a motion picture production and global sales company. The purchase price consisted of $20.4 million in cash paid at closing, and an additional $1.4 million in cash and 119,751 of Class B non-voting common shares to be paid and issued after one -year of the closing date. In addition, the Company assumed $23.6 million of corporate debt and production loans, of which $14.9 million was paid off shortly following the acquisition during the fiscal year ended March 31, 2018. The acquisition was accounted for as a purchase, with the results of operations, which were not material, of Good Universe included in the Company's consolidated results from October 12, 2017 through March 31, 2018. Based on a preliminary purchase price allocation, $29.0 million was allocated to goodwill, with the remainder primarily allocated to the fair values of investment in film and television programs, cash and cash equivalents, and other liabilities. The preliminary allocation of the estimated purchase price is based upon management's estimates and is subject to revision, as a more detailed analysis of investment in film and television programs, tax and other liabilities is completed and additional information on the fair value of assets and liabilities becomes available, including receipt of final appraisals of the net assets acquired. The goodwill recorded as part of this acquisition arises from the executive management personnel and their extensive experience and key relationships in the entertainment industry, and is included in the Motion Pictures segment (see Note 6 ). The goodwill will not be amortized for financial reporting purposes, but will be deductible for federal tax purposes. Pilgrim Media Group On November 12, 2015, the Company purchased 62.5% of the membership interests in Pilgrim Media Group, LLC ("Pilgrim Media Group"), a worldwide independent reality television producer and distributor. The aggregate purchase price was approximately $201.7 million , which consisted of $144.7 million in cash and 1,517,451 of the Company's former common shares, valued at $57.0 million . These shares were valued based on the closing price of the Company’s common shares on the date of closing of the acquisition, discounted to the fair value of the shares considering certain transfer restrictions.

At March 31, 2018, the capacity to pay dividends under the Senior Credit Facilities significantly exceeded the amount of the Company's retained earnings or net income, and therefore the Company's net income of $468.1 million and retained earnings of $516.6 million were deemed free of restrictions at March 31, 2018. In addition, a net first lien leverage maintenance covenant and an interest coverage ratio maintenance covenant apply to the Revolving Credit Facility and the Term Loan A and are tested quarterly. As of March 31, 2018 , the Company was in compliance with all applicable covenants. Change in Control. The Company may also be subject to an event of default upon a change in control (as defined in the Credit Agreement) which, among other things, includes a person or group acquiring ownership or control in excess of 50% of the Company’s common shares. 5.875% Senior Notes Interest. Bears interest at 5.875% annually. Maturity Date. November 1, 2024.

The Applicable Premium is the greater of (i) 1.0% of the principal amount redeemed and (ii) the excess of the present value of the redemption amount at November 1, 2019 (see below) of the notes redeemed plus interest through the redemption date (discounted at the treasury rate on the redemption date plus 50 basis points) over the principal amount of the notes redeemed on the redemption date. (ii) On and after November 1, 2019, redeemable by the Company, in whole or in part, at the redemption prices set forth as follows (as a percentage of the principal amount redeemed), plus accrued and unpaid interest to the redemption date: (i) on or after November 1, 2019 - 104.406% ; (ii) on or after November 1, 2020 - 102.938% ; (iii) on or after November 1, 2021 - 101.439% ; and (iv) on or after November 1, 2022 - 100% . Security. The 5.875% Senior Notes are guaranteed on an unsubordinated, unsecured basis. Covenants. The 5.875% Senior Notes contain certain restrictions and covenants that, subject to certain exceptions, limit the Company’s ability to incur additional indebtedness, pay dividends or repurchase the Company’s common shares, make certain loans or investments, and sell or otherwise dispose of certain assets subject to certain conditions, among other limitations. At March 31, 2018, the capacity to pay dividends under the 5.875% Senior Notes significantly exceeded the amount of the Company's retained earnings or net income, and therefore the Company's net income of $468.1 million and retained earnings of $516.6 million were deemed free of restrictions at March 31, 2018. As of March 31, 2018 , the Company was in compliance with all applicable covenants. Change in Control. The occurrence of a change of control will be a triggering event requiring the Company to offer to purchase from holders all of the 5.875% Senior Notes, at a price equal to 101% of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase. In addition, certain asset dispositions will be triggering events that may require the Company to use the excess proceeds from such dispositions to make an offer to purchase the 5.875% Senior Notes at 100% of their principal amount, plus accrued and unpaid interest, if any to the date of purchase. Debt Transactions Senior Credit Facilities. On December 8, 2016, Lions Gate Entertainment Corp. entered into a credit and guarantee agreement (the "Credit Agreement") which provided for a $1.0 billion five -year revolving credit facility (the "Previous Revolving Credit Facility") (ii) a $1.0 billion five -year term loan A facility (the "Previous Term Loan A") and (iii) a $2.0 billion seven -year term loan B facility (the "Previous Term Loan B"). The Previous Term Loan B was issued at 99.5% . December 2017 Previous Term Loan B Refinancing. On December 11, 2017, the Company entered into an amendment No. 1 (the "Repricing Amendment") to the Credit Agreement to reduce the interest rate on the Previous Term Loan B. In connection with the Repricing Amendment, the Company prepaid $25.0 million of principal outstanding under the Previous Term Loan B and repriced the remaining $900.0 million of principal then outstanding through the incurrence of a new six -year term loan B-1 facility in aggregate principal amount of $900.0 million (the "Previous Term Loan B-1"). The Previous Term Loan B-1 bore interest, at the Company's option, at a rate per annum equal to LIBOR (subject to a LIBOR floor of 0.75% ) plus 2.25% (or an alternative base rate plus 1.25% ) margin, which was 0.75% per annum less than the applicable margin under the Previous Term Loan B. March 2018 Senior Credit Facilities Refinancing. On March 22, 2018, the Company entered into an amendment No. 2 (the "Second Amendment") to the Credit Agreement (as amended by the Repricing Amendment and the Second Amendment, the "Amended Credit Agreement") to refinance its Previous Revolving Credit Facility, Previous Term Loan A and Previous Term Loan B-1. In connection with the Second Amendment, the Company repaid in full the then outstanding principal amounts of $950.0 million under the Previous Term Loan A and $825.0 million under the Previous Term Loan B-1, and terminated all commitments under the Previous Revolving Credit Facility. In addition, the Company incurred a new five -year Term Loan A in aggregate principal amount of $750.0 million (the "Term Loan A"), incurred a new seven -year Term Loan B in aggregate principal amount of $1,250.0 million (the "Term Loan B"), and obtained a new $1.5 billion five -year revolving credit facility (the "Revolving Credit Facility", and together with the Term Loan A and Term Loan B, the "Senior Credit Facilities"). The interest rate under the new Term Loan A and Revolving Credit Facility is LIBOR plus 1.75% . See the "Senior Credit Facilities" section above for interest rate details and required principal payments. Other Voluntary Prepayments. In addition to the prepayments in connection with the Repricing Amendment and Second Amendment described above, during the years ended March 31, 2018 and 2017, the Company made other voluntary prepayments totaling $740.0 million and $400.0 million , respectively, in principal outstanding under the Previous Term Loan B-1/ Previous Term Loan B, together with accrued and unpaid interest with respect to such principal amounts. 5.875% Senior Notes Exchange. On October 27, 2016, Lions Gate Entertainment Corp. issued $520.0 million aggregate principal amount of 5.875% senior notes due 2024 (the "2016 5.875% Senior Notes"). On March 28, 2018, in connection with a private exchange offer of the $520.0 million aggregate principal amount of its 2016 5.875% Senior Notes, an indirect, wholly owned subsidiary of the Company issued $512.3 million aggregate principal amount of new 5.875% senior notes due 2024 (the "2018 5.875% Senior Notes", and collectively with the 2016 5.875% Senior Notes, the " 5.875% Senior Notes"). The new 2018 5.875% Senior Notes were exchanged by the Company for $512.3 million of the 2016 5.875% Senior Notes. Debt Redemptions and Repayments Associated with the Starz Merger. During the year ended March 31, 2017, the Company used the proceeds of the 2016 5.875% Senior Notes, the Previous Term Loan A, the Previous Term Loan B, and a portion of the Previous Revolving Credit Facility (amounting to $50.0 million ) to finance a portion of the consideration and transaction costs for the Starz Merger (see Note 2 ) and the associated transactions, including (i) the repayment of all amounts outstanding (i.e., $241 million ) under Lionsgate's previous $800 million senior revolving credit facility issued in 2012, and such credit agreement was then terminated, (ii) the redemption of Lionsgate's previous $400 million seven -year term loan due March 2022 (the "Term Loan Due 2022"), (iii) the redemption of Lionsgate's $225.0 million outstanding principal amount of the 5.25% Senior Secured Second-Priority Notes due August 2018 (the " 5.25% Senior Notes"), (iii) the discharge of Starz's $675.0 million outstanding principal amount of the previous Starz senior notes due September 15, 2019 (the "Starz Senior Notes") that were assumed as part of the Starz Merger, and (iv) the repayment of all amounts outstanding (i.e., $255.0 million ) under Starz's existing $1.0 billion revolving credit facility that were assumed as part of the Starz Merger were repaid, and such credit agreement was then terminated. Accounting for the Debt Redemption and Repayment Transactions: Revolving Credit Facilities. Any fees paid to creditors or third parties related to the issuance of the new revolving credit facility are capitalized and amortized over the term of the new revolving credit facility. To the extent the borrowing capacity, measured as the amount available under the revolving credit facility multiplied by the remaining term, on a creditor by creditor basis, was more than under the previous revolving credit facility, any prior unamortized debt issuance costs are capitalized and amortized over the term of the new revolving credit facility. To the extent the borrowing capacity on a creditor by creditor basis was less than under the previous credit facility the prior unamortized debt issuance costs were written off as a loss on extinguishment of debt in proportion to the decrease in borrowing capacity under the former revolving credit facility. Term Loans and Senior Notes. In accounting for each contemporaneous issuance and repayment or redemption transaction discussed above, a portion of the prepayment and issuance was considered a modification of terms with creditors who participated in both the prepaid or redeemed debt and the new issuance, and a portion was considered a debt extinguishment. The previously incurred unamortized deferred financing costs, debt discount, call premiums (if any) and any fees or other amounts paid to creditors, on the prepaid or redeemed debt will be amortized over the life of the new issuance, to the extent the prepayment and issuance was considered a modification of terms, and expensed as a loss on extinguishment of debt to the extent considered an extinguishment. The new debt issuances associated with the existing creditors whose prior loans were prepaid were considered a modification of terms and therefore the new issuance costs associated with such issuances were expensed as a loss on extinguishment of debt. All costs and expenses associated with new creditors are capitalized and amortized over the life of the new issuance. Debt issuance costs and any debt discount are amortized using the effective interest method. Loss on Extinguishment of Debt. The following tables summarize the accounting for the debt issuance costs incurred and the related loss on extinguishment of debt recorded in the years ended March 31, 2018 and March 31, 2017 associated with the debt transactions discussed above ( no loss in the year ended March 31, 2016): Year Ended March 31, 2018 Loss on Extinguishment of Debt Capitalized & Amortized Over Life of New Issuances Total (Amounts in millions) New debt issuance costs $ 11.0 $ 11.6 $ 22.6 Previously incurred debt issuance costs or unamortized discount 24.7 Total $ 35.7 Year Ended March 31, 2017 Loss on Extinguishment of Debt Capitalized & Amortized Over Life of New Issuances Total (Amounts in millions) New debt issuance costs and call premium $ 20.6 $ 115.0 $ 135.6 Previously incurred debt issuance costs or unamortized discount 19.8 Total $ 40.4 Capital Lease Obligations Capital lease obligations represent lease agreements acquired in the Starz Merger (see Note 2 ). These obligations include a ten -year commercial lease for a building, with four successive five -year renewal periods at the Company's option, with an imputed annual interest rate of 7.2% , and capital lease arrangements for Starz's transponder capacity that expire from 2019 to 2023 and have imputed annual interest rates ranging from 5.5% to 7.0% .

Ltd. Under the arrangement, TIK Films, in general and subject to certain limitations including per picture and annual caps, contributed a minority share of 25% of the Company’s production or acquisition costs of “qualifying” theatrical feature films, released during the three -year period ended January 23, 2018, and participate in a pro-rata portion of the pictures’ net profits or losses similar to a co-production arrangement based on the portion of costs funded. The arrangement excluded, among others, any theatrical feature film incorporating any elements from the Twilight, Hunger Games or Divergent franchises. The percentage of the contribution could vary on certain pictures. Amounts provided from TIK Films are reflected as a participation liability in the Company's consolidated balance sheets and amounted to $151.8 million at March 31, 2018 (March 31, 2017 - $170.1 million ). The difference between the ultimate participation expected to be paid to TIK Films and the amount provided by TIK Films is amortized as a charge to or a reduction of participation expense under the individual-film-forecast method.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair Value Accounting guidance and standards about fair value define fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair Value Hierarchy Fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The accounting guidance and standards establish three levels of inputs that may be used to measure fair value: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 liabilities that are not required to be measured at fair value on a recurring basis include the Company’s convertible senior subordinated notes, production loans, 5.875% Senior Notes, Term Loan A and Term Loan B, which are priced using discounted cash flow techniques that use observable market inputs, such as LIBOR-based yield curves, swap rates, and credit ratings. • Level 3 — Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities. The Company measures the fair value of its investment in Pop's mandatorily redeemable preferred stock units using primarily a discounted cash flow analysis based on the expected cash flows of the investment. The analysis reflects the contractual terms of the investment, including the period to maturity, and uses a discount rate commensurate with the risk associated with the investment. The following table sets forth the assets and liabilities required to be carried at fair value on a recurring basis as of March 31, 2018 and 2017 : March 31, 2018 March 31, 2017 Level 1 Level 2 Total Level 1 Level 2 Total Assets: (Amounts in millions) Available-for-sale securities (see Note 5): Investment in Next Games $ 7.3 $ — $ 7.3 $ 8.0 $ — $ 8.0 Forward exchange contracts (see Note 17) — 0.3 0.3 — 0.6 0.6 Liabilities: Forward exchange contracts (see Note 17) — (0.6 ) (0.6 ) — (0.5 ) (0.5 ) $ 7.3 $ (0.3 ) $ 7.0 $ 8.0 $ 0.1 $ 8.1 The following table sets forth the carrying values and fair values of the Company’s investment in Pop's mandatorily redeemable preferred stock units and outstanding debt at March 31, 2018 and March 31, 2017 : March 31, 2018 March 31, 2017 (Amounts in millions) Carrying Value Fair Value Carrying Value Fair Value (Level 3) (Level 3) Assets: Investment in Pop's mandatorily redeemable preferred stock units $ 91.3 $ 125.0 $ 96.8 $ 122.1 Carrying Value Fair Value Carrying Value Fair Value (Level 2) (Level 2) Liabilities: Term Loan A (1) 729.7 750.9 961.8 983.8 Term Loan B (1) 1,229.3 1,251.6 1,554.7 1,610.0 5.875% Senior Notes 500.4 539.5 498.3 542.1 April 2013 1.25% Notes 60.0 60.3 60.0 58.5 Production loans 352.6 352.9 353.3 353.8 $ 2,872.0 $ 2,955.2 $ 3,428.1 $ 3,548.2 ________________ (1) As of March 31, 2017, amounts were outstanding under the Previous Term Loan A and Previous Term Loan B (see Note 7 ).

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Redeemable Noncontrolling Interests In connection with the acquisition of a controlling interest in Pilgrim Media Group on November 12, 2015, the Company recorded a redeemable noncontrolling interest of $90.1 million , representing 37.5% of Pilgrim Media Group. The noncontrolling interest holder has a right to put and the Company has a right to call a portion of the noncontrolling interest, equal to 17.5% of Pilgrim Media Group, at fair value, exercisable at five years after the acquisition date of November 12, 2015. In addition, the noncontrolling interest holder has a right to put and the Company has a right to call the remaining amount of noncontrolling interest at fair value, subject to a cap, exercisable at seven years after the acquisition date of November 12, 2015. The put and call options have been determined to be embedded in the noncontrolling interest, and because the put rights are outside the control of the Company and require partial cash settlement, the noncontrolling interest holder's interest is presented as redeemable noncontrolling interest outside of shareholders' equity on the Company's consolidated balance sheets. In addition, the noncontrolling interest holder is the President and CEO of Pilgrim Media Group. Pursuant to the operating agreement of Pilgrim Media Group, if the employment of the noncontrolling interest holder is terminated, under certain circumstances as defined in the operating agreement, the Company can call and the noncontrolling interest holder can put the noncontrolling interest at a discount to fair value. The amount of the discount related to the 17.5% noncontrolling interest is being expensed through the five -year call period, and the portion of the discount related to the remaining noncontrolling interest is being expensed over the seven -year call period. The amounts are included in general and administrative expense of Pilgrim Media Group and reflected as an addition to redeemable noncontrolling interest. Redeemable noncontrolling interests are measured at the greater of (i) the redemption amount that would be paid if settlement occurred at the balance sheet date less the amount attributed to unamortized noncontrolling interest discount if applicable, or (ii) the historical value resulting from the original acquisition date value plus or minus any earnings or loss attribution, plus the amount of unamortized noncontrolling interest discount. The amount of the redemption value in excess of the historical values of the noncontrolling interest, if any, is recognized as an increase to noncontrolling interest and a charge to retained earnings. The table below presents the reconciliation of changes in redeemable noncontrolling interests: Year Ended March 31, 2018 2017 2016 (Amounts in millions) Beginning balance $ 93.8 $ 90.5 $ — Initial fair value of redeemable noncontrolling interests — — 90.1 Net income (loss) attributable to noncontrolling interests 0.5 (0.3 ) (7.5 ) Noncontrolling interest discount accretion 6.1 5.0 2.0 Adjustments to redemption value 9.3 5.5 5.9 Cash distributions (7.9 ) (6.9 ) — Ending balance $ 101.8 $ 93.8 $ 90.5 Other Noncontrolling Interests The Company has other noncontrolling interests that are not redeemable. These noncontrolling interests primarily relate to Pantaya (a joint venture between the Company and Hemisphere Media Group), a premium Spanish-language streaming service in which the Company owns a controlling interest. The Pantaya service was launched in the three months ended September 30, 2017.

The administrator of the 2017 Plan has broad authority under the 2017 Plan to, among other things, select participants and determine the type(s) of award(s) that they are to receive, and determine the number of shares that are to be subject to awards and the terms and conditions of awards, including the price (if any) to be paid for the shares or the award. Persons eligible to receive awards under the 2017 Plan include directors of the Company, officers or employees of the Company or any of its subsidiaries, and certain consultants and advisors to the Company or any of its subsidiaries. The maximum number of Class A voting shares and Class B non-voting shares (the “Common Shares”) that may be issued or transferred pursuant to awards under the 2017 Plan (the “Share Limit”) equals: (1) the number of shares that were available for award grant purposes under the Lions Gate Entertainment Corp. 2012 Performance Incentive Plan (the “2012 Plan”) as of September 12, 2017, plus (2) the number of shares that were available for award grant purposes under the Starz 2016 Omnibus Incentive Plan (the “Starz 2016 Plan”) as of September 12, 2017, plus (3) the number of any shares subject to stock options and share appreciation rights granted under any of the 2012 Plan, the Starz 2016 Plan, the Starz 2011 Nonemployee Director Incentive Plan (Amended and Restated as of October 15, 2013), or the Starz 2011 Incentive Plan (Amended and Restated as of October 15, 2013) (collectively, the “Prior Plans”) and outstanding on September 12, 2017 which expire, or for any reason are cancelled or terminated, after that date without being exercised, plus (4) the number of any shares subject to restricted stock and restricted share unit awards granted under any of the Prior Plans that are outstanding and unvested as of September 12, 2017 which are forfeited, terminated, cancelled, or otherwise reacquired after that date without having become vested. No new awards may be granted under any of the Prior Plans. As of September 12, 2017 (immediately prior to the shareholder approval of the 2017 Plan), the total number of Common Shares available for award grant purposes under the 2012 Plan and the Starz 2016 Plan was 12,973,816 shares, and the total number of Common Shares subject to then-outstanding awards granted under the Prior Plans was 34,790,628 shares. The Common Shares available for issuance under the 2017 Plan may be either the Class A voting shares or the Class B non-voting shares, as determined by administrator of the 2017 Plan and set forth in the applicable award agreement. However, in no event may the combined number of Class A voting shares and Class B non-voting shares issued under the 2017 Plan exceed the Share Limit described above. Shares that are subject to or underlie awards which expire or for any reason are cancelled or terminated, are forfeited, fail to vest, or for any other reason are not paid or delivered under the 2017 Plan will again be available for subsequent awards under the 2017 Plan. Shares that are exchanged by a participant or withheld by the Company to pay the exercise price of an award granted under the 2017 Plan or any of the Prior Plans, as well as any shares exchanged or withheld to satisfy the tax withholding obligations related to any award granted under the 2017 Plan or any of the Prior Plans, will again be available for subsequent awards under the 2017 Plan. To the extent that an award is settled in cash or a form other than shares, the shares that would have been delivered had there been no such cash or other settlement will again be available for subsequent awards under the 2017 Plan. In the event that shares are delivered in respect of a dividend equivalent right, the actual number of shares delivered with respect to the award shall be counted against the share limits of the 2017 Plan. To the extent that shares are delivered pursuant to the exercise of a share appreciation right or stock option, the number of underlying shares as to which the exercise related shall be counted against the applicable share limits, as opposed to only counting the shares actually issued. The types of awards that may be granted under the 2017 Plan include stock options, share appreciation rights, restricted stock, restricted share units, stock bonuses and other forms of awards granted or denominated in shares or units of shares, as well as certain cash bonus awards. As is customary in incentive plans of this nature, each share limit and the number and kind of shares available under the 2017 Plan and any outstanding awards, as well as the exercise or purchase prices of awards, and performance targets under certain types of performance-based awards, are subject to adjustment in the event of certain reorganizations, mergers, combinations, recapitalizations, stock splits, stock dividends, or other similar events that change the number or kind of shares outstanding, and extraordinary dividends or distributions of property to the shareholders. 2012 Performance Incentive Plan : At the effective time of the closing of the merger, Starz had outstanding equity awards under the Starz Transitional Stock Adjustment Plan, Starz 2011 Incentive Plan, Starz 2011 Nonemployee Director Plan and Starz 2016 Omnibus Incentive Plan (collectively, the “Starz Plans”). In accordance with the Merger Agreement, at the effective time of the closing of the Starz Merger, the Company assumed the Starz Plans and the restricted stock unit awards, unvested stock options and restricted stock awards, in each case, granted under the Starz Plans (collectively, the “Assumed Awards”). As a result of this assumption, at the effective time of the closing of the Starz Merger, the Assumed Awards were converted into corresponding awards relating to Class B non-voting shares, after giving effect to appropriate adjustments to reflect the consummation of the Starz Merger. There were 30.3 million Class B non-voting shares issuable in connection with the Assumed Awards held by Starz employees and awards to be granted under the Starz Plans following the Starz Merger. The measurement of all share-based awards uses a fair value method and the recognition of the related share-based compensation expense in the consolidated financial statements is recorded over the requisite service period. Further, the Company estimates forfeitures for share-based awards that are not expected to vest. As share-based compensation expense recognized in the Company’s consolidated financial statements is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. The Company recognized the following share-based compensation expense during the years ended March 31, 2018 , 2017 and 2016: Year Ended March 31, 2018 2017 2016 (Amounts in millions) Compensation Expense: Stock options $ 43.1 $ 42.5 $ 31.0 Restricted share units and other share-based compensation 36.2 34.0 25.0 Share appreciation rights 6.3 0.6 0.3 85.6 77.1 56.3 Immediately vested restricted share units issued under annual bonus program (1) — — 22.2 Impact of accelerated vesting on equity awards (2) 2.9 2.4 — Total share-based compensation expense $ 88.5 $ 79.5 $ 78.5 Tax impact (3) (29.6 ) (28.0 ) (28.6 ) Reduction in net income $ 58.9 $ 51.5 $ 49.9 ___________________ (1) Represents the impact of immediately vested stock awards granted as part of the Company's annual bonus program, and issued in lieu of cash bonuses. (2) Represents the impact of the acceleration of certain vesting schedules for equity awards pursuant to certain severance arrangements. (3) Represents the income tax benefit recognized in the statements of income for share-based compensation arrangements. Share-based compensation expense, by expense category, consisted of the following: Year Ended March 31, 2018 2017 2016 (Amounts in millions) Compensation Expense: Direct operating $ 1.1 $ 1.2 $ — Distribution and marketing 0.9 0.4 — General and administration 83.6 75.5 78.5 Restructuring and other 2.9 2.4 — $ 88.5 $ 79.5 $ 78.5 Stock Options The following tables set forth the stock option activity during the years ended March 31, 2018 , 2017 and 2016.

Upon the closing of the Starz Merger, each outstanding share-based equity award (i.e., stock options, restricted stock, and restricted stock units) of Starz was replaced by a Class B non-voting share-based equity award (“Lions Gate replacement award”) with terms equivalent to the existing awards based on the exchange ratio set forth in the Merger Agreement. The stock option, restricted stock and restricted share unit activity from the December 8, 2016 consummation of the Starz Merger and related reclassification of the Company's shares discussed above, through March 31, 2018 is presented in the table below: Stock Options and Equity-Settled SARs (1) Class A Voting Shares Class B Non-Voting Shares Number of Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term In Years Aggregate Intrinsic Value as of March 31, 2018 Number of Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term In Years Aggregate Intrinsic Value as of March 31, 2018 Issuance of Class A voting shares and Class B non-voting shares upon reclassification of common shares at December 8, 2016 9,528,634 $25.53 9,528,634 $24.68 Issuance for Lions Gate replacement awards — — 15,395,707 $14.68 Granted 36,645 $26.03 1,783,446 $25.17 Exercised (447,140 ) $10.25 (2,198,914 ) $12.43 Forfeited or expired (28,224 ) $33.65 (207,169 ) $25.52 Outstanding at March 31, 2017 9,089,915 $26.67 24,301,704 $19.63 Granted 455,395 $30.78 2,405,095 $28.84 Exercised (537,930 ) $19.29 (2,612,877 ) $17.15 Forfeited or expired (370,943 ) $36.31 (630,807 ) $30.72 Outstanding at March 31, 2018 8,636,437 $26.93 6.31 $ 20,567,305 23,463,115 $20.56 6.17 $ 130,946,902 Outstanding as of March 31, 2018, vested or expected to vest in the future 8,606,761 $26.94 6.31 $ 20,449,524 23,317,418 $20.52 6.15 $ 130,846,866 Exercisable at March 31, 2018 5,498,184 $28.12 5.07 $ 12,157,537 16,776,803 $18.55 4.70 $ 124,449,854 _____________________________ (1) Amounts for the year ended March 31, 2017 have been reclassified to conform to the current period presentation, and now include the Company’s equity-settled share-appreciation rights ("SARs"), which were previously accounted for as cash-settled SARs. The fair value of each option award is estimated on the date of grant using a closed-form option valuation model (Black-Scholes). The following table presents the weighted average grant-date fair value of options granted in the years ended March 31, 2018, 2017 and 2016, and the weighted average applicable assumptions used in the Black-Scholes option-pricing model for stock options and share-appreciation rights granted during the years then ended: Year Ended March 31, 2018 2017 2016 Weighted average fair value of grants $8.38 $6.88 $7.64 Weighted average assumptions: Risk-free interest rate (1) 1.7% - 2.7% 1.2% - 2.4% 0.9% - 1.9% Expected option lives (in years) (2) 4 - 6 years 4 - 10 years 3 - 6 years Expected volatility for options (3) 35% 35% 35% Expected dividend yield (4) 0.0% - 1.5% 0.0% - 1.8% 0.8% - 1.8% ____________________________ (1) The risk-free rate assumed in valuing the options is based on the U.S. Treasury Yield curve in effect applied against the expected term of the option at the time of the grant. (2) The expected term of options granted represents the period of time that options granted are expected to be outstanding. (3) Expected volatilities are based on implied volatilities from traded options on the Company’s shares, historical volatility of the Company’s shares and other factors. (4) The expected dividend yield is estimated by dividing the expected annual dividend by the market price of the Company's shares at the date of grant. The total intrinsic value of options exercised as of each exercise date during the year ended March 31, 2018 was $36.9 million (2017 — $30.0 million , 2016— $15.6 million ). During the year ended March 31, 2018, 112,162 shares (2017 — 819,503 shares, 2016 — 93,210 shares) were cancelled to fund withholding tax obligations upon exercise of options. Restricted Share Units The following tables set forth the restricted share unit activity during the years ended March 31, 2018 , 2017 and 2016.

During the year ended March 31, 2018 , 674,673 shares (2017 — 1,006,888 shares, 2016 — 636,136 shares) were withheld upon the vesting of restricted stock and restricted share units. The Company becomes entitled to an income tax deduction in an amount equal to the taxable income reported by the holders of the stock options and restricted share units when vesting or exercise occurs, the restrictions are released and the shares are issued. Restricted share units are forfeited if the employees are terminated prior to vesting. The Company recognized excess tax benefits of $5.2 million associated with its equity awards in its tax benefit for the year ended March 31, 2018 ( 2017 and 2016 - none ). Other Share-Based Compensation Pursuant to the terms of certain employment agreements, during the year ended March 31, 2018, the Company granted the equivalent of $0.8 million (2017 - $1.1 million , 2016 - $1.3 million ) in shares to certain employees through the term of their employment contracts, which were recorded as compensation expense in the applicable period. Pursuant to this arrangement, for the year ended March 31, 2018, the Company issued 16,231 (2017 - 28,257 shares, 2016 - 19,578 shares), net of shares withheld to satisfy minimum tax withholding obligations. (e) Other In connection with an amendment of an affiliation agreement with a customer and effective upon the close of the Starz Merger, the Company agreed to issue to the customer three $16.67 million annual installments of equity (or cash at the Company's election). The total value of the contract of $50 million is being amortized as a reduction of revenue over the period from December 8, 2016 to August 31, 2019. During the year ended March 31, 2018, the Company issued to the customer 266,667 Class A voting shares valued at $8.3 million and 278,334 Class B non-voting shares valued at $8.3 million .

Income Tax Disclosure [Abstract]
Income Tax Disclosure	Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act (the "Tax Act") was signed into law, making significant changes to the taxation of U.S. business entities. The Tax Act reduced the U.S. corporate income tax rate from 35% to 21% , imposed a one-time transition tax in connection with the move from a worldwide tax system to a territorial tax system, provided for accelerated deductions for certain U.S. film production costs, imposed limitations on certain tax deductions such as executive compensation in future periods, and included numerous other provisions. As the Company has a March 31 fiscal year-end, the lower corporate income tax rate will be phased in, resulting in a U.S. statutory federal rate of approximately 31.5% for the fiscal year ending March 31, 2018, and 21% for subsequent fiscal years. Since we are not in a current U.S. federal tax paying position, our U.S. tax provision consists primarily of deferred tax benefits calculated at the 21% tax rate. In connection with the Tax Act, the SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”) to provide guidance to companies that have not completed their accounting for the income tax effects of the Tax Act. Under SAB 118, provisional amounts can be recorded to the extent a reasonable estimate can be made. Additional tax effects and adjustments to previously recorded provisional amounts can be recorded upon obtaining, preparing, or analyzing additional information (including computations) within one year from the enactment date of the Tax Act. The Company is currently in the process of evaluating the full impact of the Tax Act on its financial statements and has not completed this evaluation. The Company has reported provisional amounts reflecting reasonable estimates of the impact of the Tax Act, including a $165.0 million income tax benefit related to the impact of the corporate income tax rate reduction on the Company's net deferred tax liabilities. The Company has also made provisional estimates of other effects of the Tax Act, such as the measurement of deferred tax assets and liabilities related to executive compensation, the one-time transition tax, net operating loss carryovers, foreign tax credits, and accelerated deductions for U.S. film costs. The estimated impact of the Tax Act is based on a preliminary review of the new law and is subject to revision based upon further analysis and interpretation of the Tax Act. The Company will complete its accounting for the Tax Act once the Company has obtained, prepared, and analyzed all information needed (including computations) for its analysis, but no later than one year from the enactment date of the Tax Act. The Company's income tax provision (benefit) differs from the federal statutory rate multiplied by pre-tax income (loss) due to the mix of the Company's pre-tax income (loss) generated across the various jurisdictions in which the Company operates and the tax deductions generated by the Company's capital structure. In addition, the Company’s total income tax benefit of $319.4 million in fiscal 2018 includes a net benefit of $259.1 million , consisting of a $165.0 million benefit from the impact of the change in U.S. federal tax rates (discussed above) on the Company’s beginning net deferred tax liability balances, a benefit of $162.3 million primarily for foreign affiliate dividends resulting from an internal capital restructuring in connection with the Company’s third party debt refinancing (see Note 7 to the consolidated financial statements), offset by charges of $58.8 million and $9.4 million from increases in the Company’s valuation allowance associated with certain U.S. and foreign deferred tax assets, respectively, that may not be realized on a more likely than not basis. The Company's income tax provision (benefit) can be affected by many factors, including the overall level of pre-tax income, the mix of pre-tax income generated across the various jurisdictions in which the Company operates, changes in tax laws and regulations in those jurisdictions, further interpretation and legislative guidance regarding the new Tax Act, changes in valuation allowances on its deferred tax assets, tax planning strategies available to the Company, and other discrete items. The components of pretax income, net of intercompany eliminations, are as follows: Year Ended March 31, 2018 2017 2016 (Amounts in millions) United States $ (824.1 ) $ (409.2 ) $ (244.2 ) International 972.8 274.8 210.4 $ 148.7 $ (134.4 ) $ (33.8 ) The Company’s current and deferred income tax provision (benefits) are as follows: Year Ended March 31, 2018 2017 2016 Current provision (benefit): (Amounts in millions) Federal $ (17.6 ) $ 7.8 $ 6.2 States (4.3 ) 2.2 2.5 International 2.0 4.5 (0.2 ) Total current provision (benefit) $ (19.9 ) $ 14.5 $ 8.5 Deferred benefit: Federal $ (269.0 ) $ (143.3 ) $ (77.4 ) States (18.5 ) (9.9 ) (7.6 ) International (12.0 ) (10.2 ) — Total deferred benefit (299.5 ) (163.4 ) (85.0 ) Total benefit for income taxes $ (319.4 ) $ (148.9 ) $ (76.5 ) The differences between income taxes expected at U.S. statutory income tax rates and the income tax provision are as set forth below: Year Ended March 31, 2018 2017 2016 (Amounts in millions) Income taxes computed at Federal statutory rate $ 46.8 $ (47.1 ) $ (11.8 ) Foreign affiliate dividends (329.1 ) (84.2 ) (59.4 ) Foreign and provincial operations subject to different income tax rates 7.1 (14.6 ) (7.1 ) State income tax (21.2 ) (6.0 ) (3.8 ) Remeasurement of opening U.S. deferred tax liabilities due to the Tax Act (165.0 ) — — Additional remeasurements of originating deferred tax assets and liabilities 75.6 — — Transaction costs — 7.3 — Permanent differences 3.5 (0.5 ) 6.5 Other (5.3 ) (2.3 ) (0.9 ) Increase (decrease) in valuation allowance 68.2 (1.5 ) — Total benefit for income taxes $ (319.4 ) $ (148.9 ) $ (76.5 ) For the years ended March 31, 2016, 2017, and 2018, the tax provision includes a favorable permanent book-tax difference in our Canadian jurisdiction for certain foreign affiliate dividends. Canadian tax law permits such dividends to be received without being subject to tax. Although the Company is incorporated under Canadian law, the majority of its global operations are currently subject to tax in the U.S. As a result, the Company believes it is more appropriate to use the U.S. Federal statutory rate in its reconciliation of the statutory rate to its reported income tax rate. The income tax effects of temporary differences between the book value and tax basis of assets and liabilities are as follows: March 31, 2018 March 31, 2017 (Amounts in millions) Deferred tax assets: Net operating losses $ 354.5 $ 224.3 Foreign tax credits 68.3 57.5 Investment in film and television obligations 101.5 91.6 Accounts payable 78.6 112.1 Other assets 59.0 60.3 Reserves 21.4 41.2 Subordinated notes — 8.2 Total deferred tax assets 683.3 595.2 Valuation allowance (73.2 ) (5.9 ) Deferred tax assets, net of valuation allowance 610.1 589.3 Deferred tax liabilities: Intangible assets (475.5 ) (780.8 ) Fixed assets (19.5 ) (28.6 ) Accounts receivable (150.7 ) (185.7 ) Subordinated notes — — Other (17.5 ) (14.4 ) Total deferred tax liabilities $ (663.2 ) $ (1,009.5 ) Net deferred tax liabilities $ (53.1 ) $ (420.2 ) The Company has recorded valuation allowances for certain deferred tax assets, which are primarily related to U.S. foreign tax credit carryforwards as sufficient uncertainty exists regarding the future realization of these assets. At March 31, 2018 , the Company had U.S. net operating loss carryforwards ("NOLs") of approximately $1,260.5 million available to reduce future federal income taxes which expire beginning in 2029 through 2038. At March 31, 2018 , the Company had state NOLs of approximately $712.8 million available to reduce future state income taxes which expire in varying amounts beginning 2021. At March 31, 2018 , the Company had Canadian loss carryforwards of $132.5 million which will expire beginning in 2034. In addition, at March 31, 2018 , the Company had U.S. credit carryforwards related to foreign taxes paid of approximately $68.3 million to offset future federal income taxes that will expire beginning in 2021. The following table summarizes the changes to the gross unrecognized tax benefits for the years ended March 31, 2018 , 2017, and 2016: Amounts in millions Gross unrecognized tax benefits at March 31, 2015 $ 4.5 Increases related to prior year tax positions — Decreases related to prior year tax positions — Settlements — Lapse in statute of limitations — Gross unrecognized tax benefits at March 31, 2016 4.5 Increases related to prior year tax positions 14.2 Decreases related to prior year tax positions (4.5 ) Settlements — Lapse in statute of limitations — Gross unrecognized tax benefits at March 31, 2017 14.2 Increases related to current year tax position 0.1 Increases related to prior year tax positions 11.5 Decreases related to prior year tax positions (8.2 ) Settlements — Lapse in statute of limitations — Gross unrecognized tax benefits at March 31, 2018 $ 17.6 For the years ended March 31, 2018 , 2017, and 2016, interest and penalties were not significant. The Company records interest and penalties on unrecognized tax benefits as part of income tax provision. The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. With a few exceptions, the Company is subject to income tax examination by U.S. and state tax authorities for the fiscal years ended March 31, 2008 and forward. However, to the extent allowed by law, the taxing authorities may have the right to examine prior periods where NOLs were generated and carried forward, and make adjustments up to the amount of the NOLs. Currently, audits are occurring in federal and various state and local tax jurisdictions. In addition, the Company's Canadian tax returns are under examination for the years ended March 31, 2014 and March 31, 2015. The total amount of unrecognized tax benefits as of March 31, 2018 that, if realized, would affect the Company's tax benefit (provision) are $15.7 million . The Company does not believe that there are any material changes to its unrecognized tax benefits that are reasonably possible to occur within the coming year.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company’s reportable segments have been determined based on the distinct nature of their operations, the Company's internal management structure, and the financial information that is evaluated regularly by the Company's chief operating decision maker. The Company has three reportable business segments: (1) Motion Pictures, (2) Television Production and (3) Media Networks (which was not a reportable segment prior to the quarter ended December 31, 2016). Motion Pictures consists of the development and production of feature films, acquisition of North American and worldwide distribution rights, North American theatrical, home entertainment and television distribution of feature films produced and acquired, and worldwide licensing of distribution rights to feature films produced and acquired. As a result of the Starz Merger (see Note 2 ), beginning December 8, 2016, the Motion Pictures segment includes Starz's third-party distribution business. Television Production consists of the development, production and worldwide distribution of television productions including television series, television movies and mini-series, and non-fiction programming. Media Networks (which was not a reportable segment prior to the quarter ended December 31, 2016) consists of (i) Starz Networks, which includes the licensing of premium subscription video programming to U.S. multichannel video programming distributors ("MVPDs") including cable operators, satellite television providers and telecommunication companies, and over-the-top ("OTT") providers, and on a direct-to-consumer basis (ii) Content and Other, which includes the licensing of the Media Networks' original series programming to digital media platforms, international television networks, home entertainment and other ancillary markets and (iii) Streaming Services, which represents the Lionsgate legacy start-up direct to consumer streaming services on its subscription video-on-demand ("SVOD") platforms which were moved under the Media Networks segment in connection with the Starz Merger. In the ordinary course of business, the Company's reportable segments enter into transactions with one another. The most common types of intersegment transactions include licensing motion pictures or television programming from the Motion Pictures and Television Production segments to the Media Networks segment. In addition, intersegment transactions include distribution fees charged to the Media Networks segment by the Television Production segment for the distribution of Media Networks' original series programming in ancillary markets. While intersegment transactions are treated like third-party transactions to determine segment performance, the revenues (and corresponding expenses or assets recognized by the segment that is the counterparty to the transaction) are eliminated in consolidation and, therefore, do not affect consolidated results. Segment information by business unit is presented in the table below. The Media Networks segment was not previously a reportable segment prior to the quarter ended December 31, 2016, and reflects Starz Networks and Content and Other from the date of acquisition of Starz (December 8, 2016), and the Lionsgate direct to consumer streaming services on SVOD platforms for the historical periods presented.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The following table sets forth our future annual repayment of contractual commitments as of March 31, 2018 : Year Ended March 31, 2019 2020 2021 2022 2023 Thereafter Total (Amounts in millions) Contractual commitments by expected repayment date (off-balance sheet arrangements) Film obligation and production loan commitments (1) $ 566.9 $ 182.6 $ 137.5 $ 67.0 $ 14.6 $ 14.1 $ 982.7 Interest payments (2) 113.6 111.7 109.2 106.4 103.1 185.9 729.9 Operating lease commitments 24.1 25.5 30.0 23.6 29.1 34.9 167.2 Other contractual obligations 153.0 61.3 26.4 10.5 4.2 — 255.4 Total future commitments under contractual obligations (3)(4) $ 857.6 $ 381.1 $ 303.1 $ 207.5 $ 151.0 $ 234.9 $ 2,135.2 ____________________________ (1) Film obligation commitments include distribution and marketing commitments, minimum guarantee commitments and program rights commitments. Distribution and marketing commitments represent contractual commitments for future expenditures associated with distribution and marketing of films which we will distribute. The payment dates of these amounts are primarily based on the anticipated release date of the film. Minimum guarantee commitments represent contractual commitments related to the purchase of film rights for pictures to be delivered in the future. Program rights commitments represent contractual commitments under programming license agreements related to films that are not available for exhibition until some future date (see below for further details). Production loan commitments represent amounts committed for future film production and development to be funded through production financing and recorded as a production loan liability when incurred. Future payments under these commitments are based on anticipated delivery or release dates of the related film or contractual due dates of the commitment. The amounts include estimated future interest payments associated with the commitment. (2) Includes cash interest payments on the Company's debt, excluding the interest payments on the revolving credit facility as future amounts are not fixed or determinable due to fluctuating balances and interest rates. (3) Not included in the amounts above is a $869.3 million dissenting shareholders' liability associated with the Starz Merger, which is classified as a current liability based on the timing of the scheduled trial set to commence in the second half of fiscal 2019 (see Note 2 ). (4) Not included in the amounts above are $101.8 million of redeemable noncontrolling interest, as future amounts and timing are subject to a number of uncertainties such that we are unable to make sufficiently reliable estimations of future payments (see Note 11 ). The Company is obligated to pay programming fees for all qualifying films that are released theatrically in the U.S. by Sony’s Columbia Pictures, Screen Gems, Sony Pictures Classics and TriStar labels through 2021. The Company does not license films produced by Sony Pictures Animation. The programming fees to be paid by the Company to Sony are based on the quantity and domestic theatrical exhibition receipts of qualifying films. Since the term of the output programming agreement with Sony applies to all films released theatrically through December 31, 2021, the Company is obligated to pay fees for films that have not yet been released in theaters. The Company is unable to estimate the amounts to be paid under these agreements for films that have not yet been released in theaters, however, such amounts are expected to be significant. The Company has also entered into agreements with a number of other motion picture producers and are obligated to pay fees for the rights to exhibit certain films that are released by these producers. Operating Leases. The Company has operating leases for offices, back-up transponder capacity and equipment. Certain of the Company's operating leases for its Corporate and United Kingdom offices include certain lease and leasehold improvement incentives. These amounts and the required lease payments are aggregated and amortized on a straight line basis to rent expense over the lease period. The operating lease for the Company's principal office expires in August 2023. The Company incurred rental expense of $20.7 million during the year ended March 31, 2018 (2017 — $15.6 million ; 2016 — $14.2 million ). Multiemployer Benefit Plans. The Company contributes to various multiemployer pension plans under the terms of collective bargaining agreements that cover its union-represented employees. The Company makes periodic contributions to these plans in accordance with the terms of applicable collective bargaining agreements and laws but does not sponsor or administer these plans. The risks of participating in these multiemployer pension plans are different from single-employer pension plans such that (i) contributions made by the Company to the multiemployer pension plans may be used to provide benefits to employees of other participating employers; (ii) if the Company chooses to stop participating in certain of these multiemployer pension plans, it may be required to pay those plans an amount based on the underfunded status of the plan, which is referred to as a withdrawal liability; and (iii) actions taken by a participating employer that lead to a deterioration of the financial health of a multiemployer pension plan may result in the unfunded obligations of the multiemployer pension plan to be borne by its remaining participating employers. The Company does not participate in any multiemployer benefit plans that are considered to be individually significant to the Company, and as of March 31, 2018, all except two of the largest plans in which the Company participates were funded at a level of 80% or greater. The other two plans, the Motion Picture Industry Pension Plan and the Screen Actors Guild - Producers Pension Plan were funded at 67.40% and 78.15% , respectively for the 2017 plan year, but neither of these plans were considered to be in endangered, critical, or critical and declining status in the 2017 plan year. Total contributions made by the Company to multiemployer pension and other benefit plans for the years ended March 31, 2018, 2017 and 2016 were $70.9 million , $59.4 million , and $60.0 million , respectively. If the Company ceases to be obligated to make contributions or otherwise withdraws from participation in any of these plans, applicable law requires the Company to fund its allocable share of the unfunded vested benefits, which is known as a withdrawal liability. In addition, actions taken by other participating employers may lead to adverse changes in the financial condition of one of these plans, which could result in an increase in the Company's withdrawal liability. Contingencies From time to time, the Company is involved in certain claims and legal proceedings arising in the normal course of business. In addition, the matters discussed below under the captions Litigation and Appraisal have arisen in connection with the Starz Merger. The Company establishes an accrued liability for legal claims when the Company determines that a loss is both probable and the amount of the loss can be reasonably estimated. Once established, accruals are adjusted from time to time, as appropriate, in light of additional information. The amount of any loss ultimately incurred in relation to matters for which an accrual has been established may be higher or lower than the amounts accrued for such matters. Due to the inherent difficulty of predicting the outcome of litigation and claims, the Company often cannot predict what the eventual outcome of the pending matters will be, what the timing of the ultimate resolution of these matters will be, or what the eventual loss, if any, related to each pending matter may be. Accordingly, at this time, the Company has determined a loss related to these matters in excess of accrued liabilities is reasonably possible, however a reasonable estimate of the possible loss or range of loss cannot not be made at this time. The Company believes a portion of the losses that may be recognized, if any, would ultimately be recovered from insurance proceeds. Litigation Between July 19, 2016 and August 30, 2016, seven putative class action complaints were filed by purported Starz stockholders in the Court of Chancery of the State of Delaware. These actions have been consolidated into In re Starz Stockholder Litigation , Consolidated C.A. No. 12584-VCG, and the plaintiffs in the consolidated action filed a verified consolidated class action complaint on August 16, 2016. On August 18, 2016, plaintiffs filed a motion for expedited proceedings. On September 22, 2016, the court denied the motion. The defendants filed answers to the verified consolidated class action complaint on January 24, 2017. On May 17, 2018, the plaintiffs filed a verified amended consolidated class action complaint. The amended complaint names as defendants former members of the board of directors of Starz Susan Lyne, Andrew Heller, Greg Maffei, Christopher Albrecht, Daniel E. Sanchez, and Charles Y. Tanabe. The amended complaint also names as defendants Dr. Malone and Lions Gate. The amended complaint alleges, among other things, that the members of the Starz board of directors breached fiduciary duties owed to Starz and the holders of Starz Series A common stock in connection with the merger and related transactions; that Dr. Malone is a controlling stockholder of Starz who breached fiduciary duties owed to other Starz stockholders in connection with the merger and related transactions; and that Lions Gate aided and abetted such breaches of fiduciary duty. The court has entered a scheduling order providing for a trial to commence in the second half of fiscal 2019. Defendants intend to defend the action vigorously. On August 9, 2016, a putative class action complaint was filed by a purported Starz stockholder in the District Court for the City and County of Denver, Colorado: Gross v. John C. Malone, et al. , 2016-CV-32873. The complaint names as defendants the members of the board of directors of Starz, Dr. Malone and Mr. Bennett, as well as Lions Gate and Merger Sub. The complaint alleges, among other things, that the members of the Starz board of directors breached fiduciary duties owed to Starz and the holders of Starz Series A common stock in connection with the merger and the transactions contemplated by the merger agreement, and that Dr. Malone, Mr. Bennett, Lions Gate, and Merger Sub aided and abetted such breaches of fiduciary duty. On December 10, 2016, the court granted the defendants’ unopposed motion to stay the action pending final resolution of the consolidated Delaware action. On October 7, 2016, a putative class action complaint was filed by a purported Lions Gate stockholder in the Supreme Court of the State of New York for the County of Nassau: Levy v. Malone, et al. , Index No. 607759/2016. The complaint names as defendants Lions Gate and the members of its board of directors. The complaint alleges, among other things, that the members of the Lions Gate board of directors breached fiduciary duties owed to Lions Gate stockholders and/or aided and abetted breaches of fiduciary duties by others in connection with the proposed merger, and that Lions Gate and the members of its board of directors failed to disclose material information in the amended joint proxy statement/ prospectus on Form S-4/A filed on September 7, 2016 in connection with the proposed merger. On November 8, 2016, plaintiff filed a motion to preliminarily enjoin the proposed merger and for expedited discovery. On November 23, 2016, the parties entered into a stipulation of settlement resolving the action, and on November 25, 2016, filed a stipulation withdrawing plaintiff’s motion. On July 14, 2017, the court preliminarily approved the settlement, ordered that notice of the settlement be sent to class members, and scheduled a hearing for August 30, 2017 to determine whether to finally approve the settlement. On October 30, 2017, the court issued an order and judgment finally approving the settlement. Appraisal Between December 8, 2016 and March 16, 2017, five verified petitions for appraisal were filed by purported Starz stockholders in the Court of Chancery of the State of Delaware. These actions have been consolidated into In re Starz Appraisal , Consolidated C.A. No. 12968-VCG. Starz has answered the petitions, and the court has entered a scheduling order providing for a trial to commence in the second half of fiscal 2019. Starz intends to defend the action vigorously.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	Financial Instruments (a) Credit Risk Concentration of credit risk with the Company’s customers is limited due to the Company’s customer base and the diversity of its sales throughout the world. The Company performs ongoing credit evaluations and maintains a provision for potential credit losses. The Company generally does not require collateral for its trade accounts receivable. (b) Forward Contracts The Company enters into forward foreign exchange contracts to hedge its foreign currency exposures on future production expenses and tax credit receivables denominated in various foreign currencies (i.e., cash flow hedges).

Description of Business, Basis of Presentation and Significant Accounting Policies (Policies)	12 Months Ended
	Mar. 31, 2018
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Generally Accepted Accounting Principles	Generally Accepted Accounting Principles These consolidated financial statements have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”).
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements of the Company include the accounts of Lionsgate and its majority-owned and controlled subsidiaries. The Company reviews its relationships with other entities to identify whether it is the primary beneficiary of a variable interest entity (“VIE”). If the determination is made that the Company is the primary beneficiary, then the entity is consolidated. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. The most significant estimates made by management in the preparation of the financial statements relate to ultimate revenue and costs for investment in films and television programs; the allocations made in connection with the amortization of program rights; estimates of sales returns and other allowances and provisions for doubtful accounts; fair value of equity-based compensation; fair value of assets and liabilities for allocation of the purchase price of companies acquired; income taxes including the assessment of valuation allowances for deferred tax assets; accruals for contingent liabilities; and impairment assessments for investment in films and television programs, property and equipment, equity investments, goodwill and intangible assets. Actual results could differ from such estimates.
Reclassifications	Reclassifications Certain amounts presented in prior years have been reclassified to conform to the current year’s presentation.
Revenue Recognition	Revenue Recognition Revenue from the theatrical release of feature films is recognized at the time of exhibition based on the Company's participation in box office receipts. Revenue from the sale of DVDs and Blu-ray discs in the retail market, net of an allowance for estimated returns and other allowances, is recognized on the later of receipt by the customer or “street date” (when it is available for sale by the customer). Under revenue sharing arrangements, including digital and electronic-sell-through ("EST") arrangements, such as download-to-own, download-to-rent, video-on-demand and subscription video-on-demand, revenue is recognized when the Company is entitled to receipts and such receipts are determinable. Revenues from television or digital licensing for fixed fees are recognized when the feature film or television program is available to the licensee for telecast. For television licenses that include separate availability “windows” during the license period, revenue is allocated over the “windows.” Revenue from sales to international territories are recognized when access to the feature film or television program has been granted or delivery has occurred, as required under the sales contract, and the right to exploit the feature film or television program has commenced. For multiple media rights contracts with a fee for a single film or television program where the contract provides for media holdbacks (defined as contractual media release restrictions), the fee is allocated to the various media based on the Company's assessment of the relative fair value of the rights to exploit each media and is recognized as each holdback is released. For multiple-title contracts with a fee, the fee is allocated on a title-by-title basis, based on the Company's assessment of the relative fair value of each title. Programming revenue is recognized in the period during which programming is provided, pursuant to affiliation agreements. If an affiliation agreement has expired and our programming is continuing to be aired by the Distributor, revenue is recognized based on the terms of the expired agreement or the actual payment from the distributor, whichever is less. Payments to distributors for marketing support costs for which the Company does not receive a direct benefit are recorded as a reduction of revenue. Cash payments received are recorded as deferred revenue until all the conditions of revenue recognition have been met. Long-term, non-interest bearing receivables are discounted to present value.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash deposits at financial institutions and investments in money market mutual funds.
Restricted Cash	Restricted Cash Restricted cash primarily consists of amounts that are contractually designated for certain theatrical marketing obligations.
Investment in Films and Television Programs and Program Rights	Investment in Films and Television Programs and Program Rights Investment in Films and Television Programs: Investment in films and television programs includes the unamortized costs of completed films and television programs which have been produced by the Company or for which the Company has acquired distribution rights, libraries acquired as part of acquisitions of companies, films and television programs in progress and in development and home entertainment product inventory. For films and television programs produced by the Company, capitalized costs include all direct production and financing costs, capitalized interest and production overhead. For the years ended March 31, 2018 , 2017 , and 2016 , total capitalized interest was $7.9 million , $8.7 million , and $19.9 million , respectively. For acquired films and television programs, capitalized costs consist of minimum guarantee payments to acquire the distribution rights. Costs of acquiring and producing films and television programs and of acquired libraries are amortized using the individual-film-forecast method, whereby these costs are amortized and participations and residuals costs are accrued in the proportion that current year’s revenue bears to management’s estimate of ultimate revenue at the beginning of the current year expected to be recognized from the exploitation, exhibition or sale of the films or television programs. Ultimate revenue includes estimates over a period not to exceed ten years following the date of initial release of the motion picture. For an episodic television series, the period over which ultimate revenues are estimated cannot exceed ten years following the date of delivery of the first episode, or, if still in production, five years from the date of delivery of the most recent episode, if later. For titles included in acquired libraries, ultimate revenue includes estimates over a period not to exceed twenty years following the date of acquisition. Investment in films and television programs is stated at the lower of amortized cost or estimated fair value. The valuation of investment in films and television programs is reviewed on a title-by-title basis, when an event or change in circumstances indicates that the fair value of a film or television program is less than its unamortized cost. During the years ended March 31, 2018 and 2017 , the Company recorded impairment charges of $36.3 million and $22.7 million, respectively, on film and television programs. In determining the fair value of its films and television programs, the Company employs a discounted cash flows ("DCF") methodology that includes cash flows estimates of a film's ultimate revenue and costs as well as a discount rate. The discount rate utilized in the DCF analysis is based on the weighted average cost of capital of the Company plus a risk premium representing the risk associated with producing a particular film or television program. The fair value of any film costs associated with a film or television program that management plans to abandon is zero. As the primary determination of fair value is determined using a DCF model, the resulting fair value is considered a Level 3 measurement (see Note 10 ). Additional amortization is recorded in the amount by which the unamortized costs exceed the estimated fair value of the film or television program. Estimates of future revenue involve measurement uncertainty and it is therefore possible that reductions in the carrying value of investment in films and television programs may be required as a consequence of changes in management’s future revenue estimates. Films and television programs in progress include the accumulated costs of productions which have not yet been completed. Films and television programs in development include costs of acquiring film rights to books, stage plays or original screenplays and costs to adapt such projects. Such costs are capitalized and, upon commencement of production, are transferred to production costs. Projects in development are written off at the earlier of the date they are determined not to be recoverable or when abandoned, or three years from the date of the initial investment. Home entertainment product inventory consists of DVDs and Blu-ray discs and is stated at the lower of cost or market value (first-in, first-out method), and are included within other current assets on the consolidated balance sheet (see Note 18 ). Costs of DVDs and Blu-ray discs sales, including shipping and handling costs, are included in distribution and marketing expenses. Program Rights: The cost of program rights for films and television programs (including original series) exhibited by the Media Networks segment are generally amortized on a title-by-title or episode-by-episode basis over the anticipated number of exhibitions or license period. The number of exhibitions is estimated based on the number of exhibitions allowed in the agreement (if specified) and the expected usage of the content. Certain other program rights are amortized to expense on a straight-line basis over the respective lives of the agreements. Programming rights may include rights to more than one exploitation window under its output and library agreements. For films with multiple windows, the license fee is allocated between the windows based upon the proportionate estimated fair value of each window which generally results in the majority of the cost allocated to the first window on newer releases. The cost of original content in the Company's Media Networks reporting segment (see Note 15 ) is allocated between the pay television market and the ancillary revenue markets (e.g., home video, digital platforms, international television, etc.) based on the estimated relative fair values of these markets. The amount associated with the pay television market is reclassified from investment in film and television programs to program rights when the program is aired and the portion attributable to the ancillary markets remains in investment in films and television programs. All the costs of programming produced by the Media Networks segment and included in investment in films and television programs and program rights, net are classified as long term. Amounts included in program rights, other than internally produced programming, that are expected to be amortized within a year from the balance sheet date are classified as short-term.
Property and Equipment, net	Property and Equipment, net Property and equipment is carried at cost less accumulated depreciation. Depreciation is provided for on a straight line basis over the following useful lives: Distribution equipment 1 — 4 years Computer equipment and software 2 — 5 years Furniture and equipment 2 — 10 years Leasehold improvements Lease term or the useful life, whichever is shorter Building 26 years Land Not depreciated The Company periodically reviews and evaluates the recoverability of property and equipment. Where applicable, estimates of net future cash flows, on an undiscounted basis, are calculated based on future revenue estimates. If appropriate and where deemed necessary, a reduction in the carrying amount is recorded.
Investments	Investments Investments include investments accounted for under the equity method of accounting, fair value method and cost method. Equity Method Investments: The Company uses the equity method of accounting for investments in companies in which it has a minority equity interest and the ability to exert significant influence over operating decisions of the companies. Significant influence is generally presumed to exist when the Company owns between 20% and 50% of the voting interests in the investee, holds substantial management rights or holds an interest of less than 20% in an investee that is a limited liability partnership or limited liability corporation that is treated as a flow-through entity. Under the equity method of accounting, the Company's share of the investee's earnings (losses), net of intercompany eliminations, are included in the "equity interest income (loss)" line item in the consolidated statement of income. The Company records its share of the net income or loss of certain other equity method investments (see Note 5 ) on a one quarter lag and, accordingly, during the years ended March 31, 2018 , 2017 , and 2016 , the Company recorded its share of the income or loss generated by these entities for the years ended December 31, 2017, 2016 and 2015, respectively. Profit Eliminations. The Company licenses theatrical releases and other films and television programs to certain equity method investments. A portion of the profits of these licenses reflecting the Company's ownership share in the venture are eliminated through an adjustment to the equity interest income (loss) of the venture. These profits are recognized as they are realized by the equity method investee through the amortization of the related asset, recorded on the equity method investee's balance sheet, over the license period. Dividends and Other Distributions. Dividends and other distributions from equity method investees are recorded as a reduction of the Company's investment. Distributions received up to the Company's interest in the investee's retained earnings are considered returns on investments and are classified within cash flows from operating activities in the consolidated statement of cash flows. Distributions from equity method investments in excess of the Company's interest in the investee's retained earnings are considered returns of investments and are classified within cash flows provided by investing activities in the statement of cash flows. Fair Value and Cost Method Investments: Investments in companies in which the Company does not have a controlling voting interest or over which it is unable to exert significant influence are generally accounted for at fair value if the investments are publicly traded. If the investment or security is not publicly traded, the investment is accounted for at cost because its fair value is not readily determinable. Fair value investments are considered available-for-sale by the Company. Unrealized gains and losses on investments, which are available-for-sale and accounted for at fair value, are reported net of tax in accumulated other comprehensive income or loss. Impairments of Investments: The Company regularly reviews its investments for impairment, including when the carrying value of an investment exceeds its market value. If the Company determines that an investment has sustained an other-than-temporary decline in its value, the investment is written down to its fair value by a charge to earnings. Factors that are considered by the Company in determining whether an other-than-temporary decline in value has occurred include (i) the market value of the security in relation to its cost basis, (ii) the financial condition of the investee, and (iii) the Company’s intent and ability to retain the investment for a sufficient period of time to allow for recovery in the market value of the investment. For investments accounted for using the cost or equity method of accounting, the Company evaluates information available (e.g., budgets, business plans, financial statements, etc.) in addition to quoted market prices, if any, in determining whether an other-than-temporary decline in value exists. Factors indicative of an other-than-temporary decline include recurring operating losses, credit defaults and subsequent rounds of financing at an amount below the cost basis of the Company’s investment.
Intangible Assets	Intangible Assets Intangible assets acquired in business combinations are recorded at the acquisition date fair value in the Company’s consolidated balance sheet. Identifiable intangible assets with finite lives are amortized over their estimated useful lives, and identifiable intangible assets with indefinite lives are not amortized, but rather are tested annually for impairment, or sooner when circumstances indicate that the intangible asset might be impaired. Amortizable intangible assets are tested for impairment utilizing an income approach based on undiscounted cash flows upon the occurrence of certain triggering events and, if impaired, are written down to fair value. The impairment test is performed at the lowest level of cash flows associated with the asset.
Goodwill	Goodwill Goodwill represents the excess of acquisition costs over the tangible and intangible assets acquired and liabilities assumed in various business acquisitions by the Company. The Company has three reporting units with goodwill: Motion Pictures, Television Production and Media Networks. Goodwill is not amortized but is reviewed for impairment annually each fiscal year or between the annual tests if an event occurs or circumstances change that indicate it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value. The Company compares the fair value of each reporting unit to its carrying amount to determine if there is a potential goodwill impairment. If the fair value of a reporting unit is less than its carrying value, an impairment loss is recorded based on the excess of the reporting unit's carrying value over its fair value. The Company performs its annual impairment test as of January 1 in each fiscal year. Based on the Company's qualitative assessments including, but not limited to, the results of the most recent quantitative impairment test, consideration of macroeconomic conditions, industry and market conditions, cash flows, and the Company's share price, the Company concluded that it is more likely than not that the fair value of our reporting units is greater than their carrying value.
Prints, Advertising and Marketing Expenses	Advertising and Marketing Expenses The costs of prints, advertising and marketing expenses are expensed as incurred. Certain of Starz’s affiliation agreements require Starz to provide marketing support to the distributor based upon certain criteria as stipulated in the agreements. Marketing support includes cooperative advertising and marketing efforts between Starz and its distributors such as cross channel, direct mail and point of sale incentives. Marketing support is recorded as an expense and not a reduction of revenue when Starz has received a direct benefit and the fair value of such benefit is determinable. Advertising expenses for the year ended March 31, 2018 were $654.9 million ( 2017 — $588.8 million , 2016 — $470.2 million ) which were recorded as distribution and marketing expenses.
Income Taxes and Government Assistance	Income Taxes Income taxes are accounted for using an asset and liability approach for financial accounting and reporting for income taxes and recognition and measurement of deferred assets are based upon the likelihood of realization of tax benefits in future years. Under this method, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Valuation allowances are established when management determines that it is more likely than not that some portion or all of the net deferred tax asset, on a jurisdiction by jurisdiction basis, will not be realized. The financial effect of changes in tax laws or rates is accounted for in the period of enactment. From time to time, the Company engages in transactions in which the tax consequences may be subject to uncertainty. Significant judgment is required in assessing and estimating the tax consequences of these transactions. In determining the Company’s tax provision for financial reporting purposes, the Company establishes a reserve for uncertain tax positions unless such positions are determined to be more likely than not of being sustained upon examination, based on their technical merits. The Company’s policy is to recognize interest and/or penalties related to income tax matters in income tax expense. Government Assistance The Company has access to government programs that are designed to promote film and television production and distribution in certain foreign countries. The Company also has access to similar programs in certain states within the U.S. that are designed to promote film and television production in those states. Tax credits earned with respect to expenditures on qualifying film and television productions are included as an offset to investment in films and television programs when the qualifying expenditures have been incurred provided that there is reasonable assurance that the credits will be realized (see Note 18 ).
Foreign Currency Translation	Foreign Currency Translation Monetary assets and liabilities denominated in currencies other than the functional currency are translated at exchange rates in effect at the balance sheet date. Resulting unrealized and realized gains and losses are included in the consolidated statements of income. Foreign company assets and liabilities in foreign currencies are translated into U.S. dollars at the exchange rate in effect at the balance sheet date. Foreign company revenue and expense items are translated at the average rate of exchange for the fiscal year. Gains or losses arising on the translation of the accounts of foreign companies are included in accumulated other comprehensive income or loss, a separate component of shareholders’ equity.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Derivative financial instruments are used by the Company in the management of its foreign currency exposures. The Company’s policy is not to use derivative financial instruments for trading or speculative purposes. The Company enters into forward foreign exchange contracts to hedge its foreign currency exposures on future production expenses denominated in various foreign currencies. The Company evaluates whether the foreign exchange contracts qualify for hedge accounting at the inception of the contract. The fair value of the forward exchange contracts is recorded on the consolidated balance sheets. Changes in the fair value of the foreign exchange contracts that are effective hedges are reflected in accumulated other comprehensive income or loss, a separate component of shareholders’ equity, and changes in the fair value of foreign exchange contracts that are ineffective hedges are reflected in the consolidated statements of income. Gains and losses realized upon settlement of the foreign exchange contracts that are effective hedges are amortized to the consolidated statements of income on the same basis as the production expenses being hedged.
Share-Based Compensation	Share-Based Compensation The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. The fair value is recognized in earnings over the period during which an employee is required to provide service. See Note 12 for further discussion of the Company’s share-based compensation.
Net Income Per Share	Net Income Per Share Basic net income per share is calculated based on the weighted average common shares outstanding for the period. Basic net income per share for the years ended March 31, 2018 , 2017 and 2016 is presented below: Year Ended March 31, 2018 2017 2016 (Amounts in millions, except per share amounts) Basic Net Income Per Common Share: Numerator: Net income attributable to Lions Gate Entertainment Corp. shareholders $ 473.6 $ 14.8 $ 50.2 Denominator: Weighted average common shares outstanding 208.4 165.0 148.5 Basic net income per common share $ 2.27 $ 0.09 $ 0.34 Diluted net income per common share reflects the potential dilutive effect, if any, of the conversion of convertible senior subordinated notes under the "if converted" method. Diluted net income per common share also reflects share purchase options, including equity-settled share appreciation rights ("SARs"), restricted share units ("RSUs") and restricted stock using the treasury stock method when dilutive, and any contingently issuable shares when dilutive. Diluted net income per common share for the years ended March 31, 2018 , 2017 and 2016 is presented below: Year Ended March 31, 2018 2017 2016 (Amounts in millions, except per share amounts) Diluted Net Income Per Common Share: Numerator: Net income attributable to Lions Gate Entertainment Corp. shareholders $ 473.6 $ 14.8 $ 50.2 Add: Interest on convertible notes, net of tax 0.5 — 0.5 Numerator for diluted net income per common share $ 474.1 $ 14.8 $ 50.7 Denominator: Weighted average common shares outstanding 208.4 165.0 148.5 Effect of dilutive securities: Conversion of notes 2.1 — 2.1 Share purchase options 7.5 3.5 3.1 Restricted share units and restricted stock 0.7 0.3 0.4 Contingently issuable shares 1.7 3.4 — Adjusted weighted average common shares outstanding 220.4 172.2 154.1 Diluted net income per common share $ 2.15 $ 0.09 $ 0.33 For the years ended March 31, 2018 , 2017 and 2016 , the outstanding common shares issuable presented below were excluded from diluted net income per common share because their inclusion would have had an anti-dilutive effect.

Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Guidance Adopted in Fiscal 2018 Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities : In August 2017, the Financial Accounting Standards Board ("FASB") issued guidance which amends its hedge accounting model to enable entities to better portray their risk management activities in the financial statements. The amendments expand an entity's ability to hedge nonfinancial and financial risk components and reduce complexity in fair value hedges of interest rate risk. The new guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The new guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. The guidance is effective for the Company's fiscal year beginning April 1, 2019, with early adoption permitted. The Company adopted this new guidance in the fourth quarter of the fiscal year ended March 31, 2018, effective April 1, 2017, with no material impact on the Company's consolidated financial statements. Employee Share-Based Payment Accounting : In March 2016, the FASB issued amended guidance related to employee share-based payment accounting. The Company adopted this new guidance effective April 1, 2017. The new guidance and the impact on the consolidated financial statements upon adoption are summarized as follows: • Excess Tax Benefits and Tax Deficiencies: Effective on a prospective basis, excess tax benefits and deficiencies that arise when share-based awards vest or are settled are recognized in the income statement. In addition, the new guidance eliminates the requirement that excess tax benefits be realized (i.e., through a reduction in income taxes payable) before companies can recognize them. Under the previous guidance, the tax effects were recorded in additional paid-in capital, when realized. Historically, the Company has not recorded significant excess tax benefits, because such benefits have not been realized. Upon adoption, the Company recorded a cumulative-effect adjustment of $54.3 million in retained earnings for the net excess tax benefits not previously realized. • Statement of Cash Flows Presentation: The new guidance requires presentation of excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity, and requires presentation of cash paid to a tax authority when shares are withheld to satisfy the employer's statutory income tax withholding obligation as a financing activity. The Company applied the change to the presentation of excess tax benefits as an operating activity on a retrospective basis; however, there was no impact to the statement of cash flows since there were no excess tax benefits in the consolidated statements of cash flows for the years ended March 31, 2017 and 2016. The Company has historically presented cash paid for shares withheld to satisfy employee taxes as a financing activity in the consolidated statements of cash flows, and accordingly there was no impact from adopting this aspect of the standard. • Forfeitures: The new guidance provides for an election to account for forfeitures of share-based payments either by (1) recognizing forfeitures of awards as they occur or (2) estimating the number of awards expected to be forfeited and adjusting the estimate when it is likely to change (as is required under the previous guidance). As allowed by the standard, the Company elected to continue to estimate potential forfeitures. • Statutory Withholding: The new guidance increases the amount companies can withhold to cover income taxes on awards without triggering liability classification for shares used to satisfy statutory income tax withholding obligations and requires application of a modified retrospective transition method. There was no material impact upon adoption related to this change. Equity Method of Accounting : In March 2016, the FASB issued guidance that changes the requirements for equity method accounting when an investment qualifies for use of the equity method as a result of an increase in the investor’s ownership interest in or degree of influence over an investee. The guidance (i) eliminates the need to retroactively apply the equity method of accounting upon qualifying for such treatment, (ii) requires that the cost of acquiring the additional interest in an investee be added to the basis of the previously held interest and (iii) requires that unrealized holding gains or losses for available-for-sale equity securities that qualify for the equity method of accounting be recognized in earnings at the date the investment becomes qualified for use of the equity method of accounting. The Company adopted the new guidance effective April 1, 2017, with no material impact on the Company's consolidated financial statements. Intra-Entity Transfers of Assets Other Than Inventory : In October 2016, the FASB issued guidance that will require the tax effects of intercompany transactions, other than sales of inventory, to be recognized when the transfer occurs, eliminating an exception under current U.S. GAAP in which the tax effects of intra-entity asset transfers are deferred until the transferred asset is sold to a third party or otherwise recovered through use. This guidance is effective for the Company's fiscal year beginning April 1, 2018, with early adoption permitted. Upon adoption, the cumulative-effect of the new standard is to be recorded as an adjustment to retained earnings. The Company adopted this guidance, effective April 1, 2017, and as a result, the Company recorded a cumulative-effect adjustment of $6.5 million in retained earnings for the tax effects (net benefit) of intra-entity transfers. Under the new guidance, the consolidated tax benefit in the year ended March 31, 2018 was $3.0 million lower, respectively, than would have been recorded under the previous guidance. Accounting Guidance Not Yet Adopted Revenue Recognition : In May 2014, the FASB issued an accounting standard update relating to the recognition of revenue from contracts with customers, which will supersede most current U.S. GAAP revenue recognition guidance, including industry-specific guidance. The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized. In addition, this guidance requires new or expanded disclosures related to revenues recognized. The new framework will become effective on April 1, 2018. The Company has elected the modified retrospective approach and will apply the new revenue standard beginning April 1, 2018. The Company has completed its assessment of the changes required by the new guidance, and while the Company does not expect that the adoption will have a material impact on the Company's reported operating results, the impact of the Sales or Usage Based Royalties acceleration discussed below will depend on the timing and performance of film and television releases in future periods. Upon adoption of the new guidance, the Company will record an adjustment to retained earnings for the cumulative effect of open contracts as of April 1, 2018. The Company has not completed its final calculation of the cumulative effect adjustment to be recorded to retained earnings; however, the Company expects this adjustment to be an increase to retained earnings of less than $25 million . In addition, the Company has designed appropriate changes to the Company’s processes, systems and controls to support the recognition and disclosure requirements under the new standard. The Company has identified certain significant areas in which the Company's revenue recognition is expected to change as compared with historical GAAP, as follows: Sales or Usage Based Royalties: The Company currently receives royalties from certain international distributors and other transactional digital distribution partners based on the sales made by these distributors after recoupment of a minimum guarantee, if applicable. The Company currently records these sales and usage based royalties after receiving statements from the licensee and/or film distributor. Under the new revenue recognition rules, revenues will be recorded based on best estimates available in the period of sales or usage. Accordingly, the timing of the revenue recognition will be accelerated; however, the Company will continue to have a consistent number of periods of sales or usage based royalties earned in each period, and therefore the impact of the new guidance will depend on the timing and performance of the titles released in those periods. Renewals of Licenses of Intellectual Property: Under the current guidance, when the term of an existing license agreement is extended, without any other changes to the provisions of the license, revenue for the renewal period is recognized when the agreement is renewed or extended. Under the new guidance, revenue associated with renewals or extensions of existing license agreements will be recognized as revenue when the license content becomes available under the renewal or extension. This change will impact the timing of revenue recognition as compared with current revenue recognition guidance. While revenues from renewal do occur, they are not a significant portion of our revenue and thus are not expected to have a material impact on our revenue recognition. Licenses of Symbolic Intellectual Property: Certain intellectual property, such as brands, tradenames and logos, is categorized in the new guidance as symbolic. Under the new guidance, a licensee’s ability to derive benefit from a license of symbolic intellectual property is assumed to depend on the licensor continuing to support or maintain the intellectual property throughout the license term. Accordingly, under the new guidance, revenue from licenses of symbolic intellectual property is generally recognized over the corresponding license term. Therefore, the new guidance will impact the timing of revenue recognition as compared to current guidance. The Company does not currently have a significant amount of revenue from the license of symbolic intellectual property. Non-Refundable Minimum Guarantees Applied Against Variable Fees Related to a Group of Films: Under the current guidance, when a licensing arrangement provides for a nonrefundable minimum guarantee that is applied against variable fees from a group of films on a cross-collateralized basis, revenue is deferred and recognized as the customer exhibits or exploits the film, on a film-by-film basis, based on the film's performance under the arrangement. Under the new guidance, the nonrefundable minimum guarantee associated with such a licensing arrangement will be allocated to the group of films and recognized as revenue on a film-by-film basis when the performance obligation for each film is met. This change is expected to accelerate the timing of revenue recognition under these licensing arrangements, as compared to the current guidance. The Company does not currently have a significant amount of revenue from these licensing arrangements. Principal vs. Agent: The new standard includes new guidance as to how to determine whether the Company is acting as a principal, in which case revenue would be recognized on a gross basis, or whether the Company is acting as an agent, in which case revenues would be recognized on a net basis. The Company does not expect the new principal versus agent guidance to have a material impact (i.e., changing from gross to net recognition or from net to gross recognition) under its existing distribution arrangements. Recognition and Measurement of Financial Instruments : In January 2016, the FASB issued new guidance that addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Among other provisions, the new guidance requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. For investments without readily determinable fair values, entities have the option to either measure these investments at fair value or at cost adjusted for changes in observable prices minus impairment. The guidance is effective for the Company's fiscal year beginning April 1, 2018. Early adoption is not permitted, except for certain provisions relating to financial liabilities. Upon adoption of the new guidance, the Company will record a transition adjustment, expected to be approximately $3.2 million , to reclassify the unrealized gains recorded through March 31, 2018 for the Company's available-for-sale investments with a readily determinable fair market value (i.e., Next Games) from accumulated other comprehensive income (loss) to retained earnings. After adoption of the new guidance, changes in the fair value of the Company's available-for-sale investments with a readily determinable fair market value will be recognized in net income. The adoption of the new guidance will also impact the accounting for the Company's cost method investments, which will be measured at cost less any impairment, adjusted for observable price changes in orderly transactions in the investees' securities that are identical or similar to the Company's investments in the investee. The impact of this change will depend on the nature and extent of changes in observable prices, if any. See Note 5 . Accounting for Leases : In February 2016, the FASB issued guidance on accounting for leases which requires lessees to recognize most leases on their balance sheets for the rights and obligations created by those leases. The new guidance also requires additional qualitative and quantitative disclosures related to the nature, timing and uncertainty of cash flows arising from leases. The guidance is effective for the Company's fiscal year beginning April 1, 2019, with early adoption permitted, and is required to be implemented using a modified retrospective approach. The Company is currently evaluating the impact that the adoption of this new guidance will have on its consolidated financial statements. Classification of Certain Cash Receipts and Cash Payments : In August 2016, the FASB issued guidance that clarifies how entities should classify certain cash receipts and payments on the statement of cash flows. The guidance primarily relates to the classification of cash flows associated with certain (i) debt transactions including debt prepayment or extinguishment costs, (ii) contingent consideration arrangements related to a business combination, (iii) insurance claims and policies, (iv) distributions from equity method investees and (v) securitization transactions. This guidance is effective for the Company's fiscal year beginning April 1, 2018, with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements. Restricted Cash : In November 2016, the FASB issued guidance to clarify how entities should present restricted cash and restricted cash equivalents in the statement of cash flows. The guidance requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. The guidance will be applied retrospectively and is effective for the Company’s fiscal year beginning April 1, 2018, with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements. Definition of a Business : In January 2017, the FASB issued guidance that changes the definition of a business for accounting purposes. Under the new guidance, an entity first determines whether substantially all of the fair value of a set of assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set of assets is not deemed to be a business. If the threshold is not met, the entity then evaluates whether the set of assets meets the requirement to be deemed a business, which at a minimum, requires there to be an input and a substantive process that together significantly contribute to the ability to create outputs. The guidance is effective on a prospective basis for the Company's fiscal year beginning April 1, 2018. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements. Stock Compensation - Scope of Modification Accounting : In May 2017, the FASB issued guidance which clarifies that an entity will not apply modification accounting to a share-based payment award if all of the fair value, vesting conditions, and classification of the modified award as an equity or liability instrument are the same immediately before and after the modification. The guidance will be applied prospectively, and is effective for the Company's fiscal year beginning April 1, 2018, with early adoption permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

Summary of Estimated Purchase Consideration	The following table summarizes the components of the estimated purchase consideration, inclusive of Lions Gate’s existing ownership of Starz common stock and Starz’s share-based equity awards outstanding as of December 8, 2016: (Amounts in millions) Market value, as of December 8, 2016, of Starz Series A and Series B common stock already owned by Lionsgate (1) $ 179.3 Cash consideration paid to Starz stockholders Starz Series A common stock at $18.00 $ 1,123.3 Starz Series B common stock at $7.26 52.8 1,176.1 Fair value of Lionsgate voting and non-voting shares issued to Starz's stockholders Starz Series A common stock at exchange ratio of 0.6784 Lionsgate non-voting shares $ 1,088.0 Starz Series B common stock at exchange ratio of 0.6321 Lionsgate voting shares 121.6 Starz Series B common stock at exchange ratio of 0.6321 Lionsgate non-voting shares 118.1 1,327.7 Replacement of Starz share-based payment awards (2) 186.5 Liability for dissenting shareholders 797.3 Total purchase consideration $ 3,666.9 (1) The difference between the fair value of the Starz available-for-sale securities owned by Lionsgate and the original cost of the Starz available-for-sale securities of $158.9 million , amounting to $20.4 million , was reflected as a gain on Starz investment in the consolidated statement of income for the fiscal year ended March 31, 2017. (2) Upon the closing of the merger, each outstanding share-based equity award (i.e., stock options, restricted stock, and restricted stock units) of Starz was replaced by a Lions Gate non-voting share-based equity award (“Lions Gate replacement award”) with terms equivalent to the existing awards based on the exchange ratio set forth in the Merger Agreement. Each Starz outstanding award was measured at fair value on the date of acquisition and the portion attributable to pre-combination service was recorded as part of the purchase consideration. The fair value of the Lions Gate replacement award measured on the date of acquisition in excess of the fair value of the Starz award attributed to and recorded as part of the purchase consideration was attributed to post-combination services and is being recognized as share-based compensation expense over the remaining post-combination service period. The estimated aggregate fair value of the Lions Gate replacement awards to be recorded as part of the purchase consideration is $186.5 million , and the estimated remaining aggregate fair value totaling $43.3 million will be recognized in future periods in accordance with each respective award’s vesting terms. The fair value of the Lions Gate replacement restricted stock and restricted stock unit awards was determined based on the value estimated for the Class A voting shares and Class B non-voting shares as of the acquisition date as discussed above. The fair value of Lions Gate replacement stock option awards was determined using the Black-Scholes option valuation model using the estimated fair value of the Class B non-voting shares underlying the replacement stock options. For purposes of valuing the Lions Gate replacement awards, the following weighted-average applicable assumptions were used in the Black-Scholes option valuation model: Weighted average assumptions: Risk-free interest rate 0.39% - 1.83% Expected option lives (years) 0.01 - 5.50 years Expected volatility 35% Expected dividend yield 0% The risk-free rate assumed in valuing the options is based on the U.S. Treasury Yield curve in effect applied against the expected term of the option at the time of the grant. The expected option lives represents the period of time that options are expected to be outstanding. Expected volatilities are based on implied volatilities from traded options on Lions Gate’s stock, historical volatility of Lions Gate’s stock and other factors. The expected dividend yield was zero since the combined company had suspended the quarterly dividend.
Fair Value Assumptions in Replacement Awards	For purposes of valuing the Lions Gate replacement awards, the following weighted-average applicable assumptions were used in the Black-Scholes option valuation model: Weighted average assumptions: Risk-free interest rate 0.39% - 1.83% Expected option lives (years) 0.01 - 5.50 years Expected volatility 35% Expected dividend yield 0%

[3]	Film obligation commitments include distribution and marketing commitments, minimum guarantee commitments and program rights commitments. Distribution and marketing commitments represent contractual commitments for future expenditures associated with distribution and marketing of films which we will distribute. The payment dates of these amounts are primarily based on the anticipated release date of the film. Minimum guarantee commitments represent contractual commitments related to the purchase of film rights for pictures to be delivered in the future. Program rights commitments represent contractual commitments under programming license agreements related to films that are not available for exhibition until some future date (see below for further details). Production loan commitments represent amounts committed for future film production and development to be funded through production financing and recorded as a production loan liability when incurred. Future payments under these commitments are based on anticipated delivery or release dates of the related film or contractual due dates of the commitment. The amounts include estimated future interest payments associated with the commitment.
[4]	Includes cash interest payments on the Company's debt, excluding the interest payments on the revolving credit facility as future amounts are not fixed or determinable due to fluctuating balances and interest rates.
